Assuming this is all he does to solve the equation, it would look like this:
9y = 54
He solves this by dividing 54 by 9:
y = 54/9
y = 6
1) Write down the equation for the theorem. 2) Replace the sides you know. 3) Solve the resulting equation for the third side.
Math should grow up and learn to solve it's own problems ^^Hope This Helps!
It's not always to 'solve' as it is to 'simplify' EX: 15a + 3b = 45c simplifies to 5a + b = 15c
You never "move" things "to the other side" of an equation. The onlypermissible treatment of an equation is to perform the same operationon both sides.Let's have a look at this one:(x)-0.5 = 1A negative exponent means the reciprocal of the positive one,so you can write:1/(x)0.5 = 1You haven't changed anything or performed any operation, onlywritten the left side in a different way.Now it's time to think about the meaning of an exponent of 1/2 .It means "square root", so there's another way to write the left side:1/sqrt(x) = 1We still haven't performed any operations, only found different waysto write the left side. Now we can do some operations to solve for 'x'.Multiply each side of the equation by sqrt(x):1 = sqrt(x)Square both sides of the equation:1 = xWhat was so mysterious or complicated about that ?
Normally you would need the remainder of the equation to solve it. However, anything times one equals itself, so the answer (in part) is "2y". Remember, you can't solve the equation fully without finding the value of 'y', and you cannot find the value of 'y' unless you know what resides on the other side of the equal sign.
3n=36 Write the equation n=12 Divide each side of the equation by 3 to get the variable alone.
Here are the steps: -- Write the equation. -- Subtract 7 from each side of the equation. -- Subtract 4x from each side. -- Divide each side by 5.
x - 9 = 15Add 9 to each side of the equation:x = 24
Here are the steps: -- Write the equation. -- Combine like terms on the right side. -- Add 10 to each side of the equation. -- Subtract 2b from each side. -- Divide each side by 2 .
Divide each side of the equation by 10 .
1) Write down the equation for the theorem. 2) Replace the sides you know. 3) Solve the resulting equation for the third side.
You solve just like any other equation: You try to manipulate your equation so that the "x" is alone on the left side, and everything else on the right side.
NO!
Algebraically manipulate the equation until you have the indicated variable on one side of the equation and all of the other factors on the other side.
First, subtract 3x from each side of the equation. Then, divide each side of the equation by 7 .
There is no equation in the question, only an expression. An expression cannot be solved.
A two-step equation is an equation that requires two steps to solve We must eliminate any constant that is on the same side as the variable first To solve, use the inverse operations to isolate the variable by itself Remember whatever you do to one side, you must do to the other
