Question

Solve for b open image

Answer 1

130

Explanation:

2x+100=5x+55

subtract 55 from both sides

2x+45=5x

minus 2x

45=3x

divide by 3

x=15

plug it in

2(15)+100=130

Answer 2

Explanation:

`2x + 100 = 5x + 55 \\ 100 - 55 = 5x - 2x \\ 45 = 3x \\ (3x)/(3) = (45)/(3) \\ x = 15`

so,2(15)+100=130
