Question

Given the notation solve and determine what number x has to be in order for it to equal zero

-2x+12=0

Answer 1

Answer: x = 6

Explanation:

Solve for x in the equation.

-2x + 12 = 0 subtract 12 from both sides

- 12 -12

-2x = -12 Divide both sides by -2

x = 6

Now input 6 into the equation for x and check if it is true.

-2(6) + 12 = 0

-12 + 12 = 0

0 = 0

x is indeed 6.
