Question

Solve for b open image

Answer 1

Answer:

130

Step-by-step 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

Step-by-step explanation:

$2x + 100 = 5x + 55 \\ 100 - 55 = 5x - 2x \\ 45 = 3x \\ \frac{3x}{3} = \frac{45}{3} \\ x = 15$

so,2(15)+100=130
