Question

How would you solve the following equation: x - 10 = 90

Answer 1

To solve the equation x - 10 = 90, you can add 10 to both sides of the equation to get:

x - 10 + 10 = 90 + 10

x = 100

Therefore, the solution to the equation is x = 100.

You can also check this solution by substituting it back into the original equation:

x - 10 = 90

100 - 10 = 90

90 = 90

This confirms that x = 100 is a valid solution to the equation.

Answer 2

9. You are solving for the variable, x. Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x, by adding 10 to both sides of the equation:

`x - 10 = 90\\x - 10 (+10) = 90 (+10)\\x = 90 + 10\\x = 100`

a. Add 10 to both sides.

10. You are solving for the variable, x. Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x, by multiplying 5 to both sides of the equation:

`(x)/(5) = 5\\ ((x)/(5)) (* 5) = 5 (*5)\\x = 5 * 5\\x = 25`

d. Multiply both sides by 5.
