Question

What is the solution to this equation?

–0.2(x – 20) = 44 – x
A. x = –90
B. x = –50
C. x = 50
D. x = 90

Answer 1

x = 50

Isolate the variable by dividing each side by factors that don't contain the variable. x=50 this is helpful

Answer 2

C

Explanation:

-0.2(x-20)=44-x

Divide both sides by -0.2:

x-20=-220+5x

Subtract x from both sides:

-20=-220+4x

Add 220 to both sides:

200=4x

x=50, or answer choice C. Hope this helps!
