Question

Solve -3.4 - x = -2 1/2


Please include explanation!!​

Answer 1

x = -0.9

Explanation:

You need to isolate x in order to find x so,

-3.4 - x = -2 1/2 or -2.5

-3.4 - x = -2.5

Add 3.4 to -2.5

-3.4 - x = -2.5

+3.4 +3.4

-x = 0.9

x CANNOT be negative so divide -1 to both sides

-x/-1 = 0.9/-1

x = -0.9

Checking answer

-3.4 - (-0.9) = -2.5

-3.4 + 0.9 = -2.5

-2.5 = -2.5
