Which value of x makes the equation true? 80 - 2x = 100

1 answer

To find the value of x that makes the equation true, we can solve for x.

80 - 2x = 100

First, let's subtract 80 from both sides:

-2x = 100 - 80

This simplifies to:

-2x = 20

Next, we'll divide both sides by -2 to isolate x:

x = 20 / -2

x = -10

Therefore, the value of x that makes the equation true is -10.
