# What must you do to make the equation 81 x 9 equals 801 true?

x*x*x=y

### Solve for x 3 - x 7?

Sorry. I can't solve that because it is not an equation. An equation has an equals sign, and a solution is a set of assignments to the variables of the equation that would make it true. For example: 2x - 3 = 5 That's an equation because it has an equals sign. There is only one real solution, x=4, because when x equals 4, the equation is true, and when x equals any other real…

### Can you explain why the equation 4x plus 3 equals 4x plus 1 has no solution?

The trivial answer is: Because there is no possible number that 'x' can be and make the equation a true statement. If the equation is true ... if the left side is actually equal to the right side ... then it must still be true after we subtract the same thing from both sides. Let us subtract 4x from both sides. Then we have 3 = 1 . That statement is clearly not true. So…

### Rewrite the following equation by moving only one digit to make it a true equation 62 - 63 equals 1?

### What is -16 plus t equals 7?

It is a linear equation in 't'. The solution is the number that 't' must be in order to make it a true statement. Here is the highly detailed description of the complex process that must be carefully followed in order to find the solution: Step #1: Write the equation: -16 + t = 7 Step #2: Add 16 to each side of the equation: t = 23
