Question

Solve for x. −7.8 (x + 6.5)= −25.74

Answer 1

Simplify both sides of the equation. (Distribute)
(−7.8)(x)+(−7.8)(6.5)=−25.74   −7.8x + −50.7= −25.74 ------------->  −7.8x − 50.7= −25.74
Add 50.7 to both sides.
−7.8x − 50.7 + 50.7 =  −25.74 + 50.7 ---------------------> −7.8x = 24.96
Divide both sides by -7.8.
−7.8x /−7.8   =   24.96/−7.8


X= −3.2   :D

Answer 2

Divide both sides by -7.8
x+6.5=3.3
minus 6.5 from both sides
x=-3.2
