Question

2) If -5 +4x = 6x, then 4x = ?
A) 5/2
B)-10
C)-5/2
D)-20

Answer 1

Explanation:

-5 +4x = 6x

add5 : -5 +4x+5 = 6x+5

4x= 6x+5

Answer 2

Answer: B) -10

Work Shown:

-5 + 4x = 6x

-5 + 4x - 4x = 6x - 4x ... subtract 4x from both sides

-5 = 2x

2x = -5

2*2x = 2(-5) ... multiply both sides by 2, see note below

4x = -10

note: Alternatively, you can solve 2x = -5 for x to get x = -5/2, then multiply both sides by 4 to end up with 4x = -10.
