Question

Solve the equation below. -4 – 0.2x + 11 = -0.8x + 10. A : x=5 B : x=-5 C : x=10 D x=2​

Answer 1

A

Explanation:

given the equation

- 4 - 0.2x + 11 = - 0.8x + 10 ( simplify left side )

- 0.2x + 7 = - 0.8x + 10 ( add 0.8x to both sides )

0.6x + 7 = 10 ( subtract 7 from both sides )

0.6x = 3 ( divide both sides by 0.6 )

x =
`(3)/(0.6)` = 5
