Question

Solve each of the following equations for the missing variable.

Answer 1

Answer:

x = -20

Step-by-step explanation:

$- 2.5x - 10 = 40$

Collect like terms and simplify

$- 2.5x = 40 + 10 \\ - 2.5x = 50$

Divide both sides of the equation by -2.5

$\frac{ - 2.5x}{ - 2.5} = \frac{50}{ - 2.5}$

Simplify

$x = - 20$

Answer 2

The answer for -2.5x-10=40 would be:
x = - 20.
