Take 3 from each side: 8x = 56

Divide by 8: x = 7

Next business?

This system has the unique solution (7, -1). Solving the first equation for x and substituting gives us y = -1; substituting that into either of the original equations gives x = 7.

3y means that the value of the variable 'y' is multiplied by 3

Three ranges.

-1

Put in function/point slope form.

X - 3Y = 6

- 3Y = - X + 6

Y = (1/3)X - 2

-----------------

zero out the Y

(1/3)X - 2 = 0

(1/3)X = 2

2 divided by 1/3 same as 2 * 3/1 = 6

X = 6

-----------------

of course you can just zero out the Y in original equation

X - 3(0) = 6

X = 6

--------

it equals -9

-17

639 = 32 x 71

x/2 + 29 = 24

Subtract 29 from both sides: x/2 = -5

Multiply both sides by 2: x = -10

x + 3 = 2x + 4

Subtract x from both sides: 3 = x + 4

Subtract 4 from both sides: - 1 = x

y = x + 3 = -1 + 3 = 2

The solution is (x, y) = (-1, 2)

The strict answer to this question is that it is an equation. Being an accomplished mind-reader I believe you wish to know the value of x. So add 2x to each side to get -17=6+x, then subtract 6 from each side to get -23 = x

Water displacement

Say you have 4/10 2 goes into 4 2 time and 10 5 times so is 2/5 when you have an even and a odd you can't simplify

1in = 2.54cm

0.2cm x 1in/2.54cm = 0.08in

A single linear equation in two variables cannot be solved: you need two independent equations.

You don't need to put any in as BODMAS tells you to do the multiplication first, but to clarify this you can put them around the multiplication:

2 + -3 x 4 = 2 + (-3 x 4)

well, the formula is A=pi(r)^2 r=radius A=area ^=to the [insert number here] power pi=3.14...

Call one of the numbers x. Since the sum is 390, the other must be 390 - x. Thus we have x(390 - x) = 34304. Solving this quadratic equation, we find the numbers are

134 and 256.

Change engines. It would take a donor car and lots of work by someone who knew what they were doing. Forget going that route. Sell the 4 cylinder and buy a V6 if that is what you want.

it is already out. go check it out at radicalplay.com

This question doesn't work, as there are two variables. When you have more than one variable, it means that you need the same number of equations as the variables. So if you have x and y, you cannot just have the equation -3x + y=8. You need another one.
