The letter b represents a nonzero constant. Solve 2bx-bx=-8 for x

Question

 The letter b represents a nonzero constant. Solve 2bx-bx=-8 for x

Answer 1

2bx - bx = -8

(2 - 1)bx = -8 (Factor bx)

bx = -8 (Combine like terms)

x = -8/b (Divide b on both sides to get x by itself)

Answer 2

2bx-bx is the same as two bx - one bx = one bx = bx

so bx = -8

x =-8/b where b can be any number other than zero

since b can be negative or positive, x can be any number, except zero also

Answer 3

2bx-bx=-8

First factor out the x:

x(2b-b)=-8

Combine like terms:

x(b)=-8

Divide to isolate x:

x=-8/b
