Solve for b open image

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
Step-by-step explanation:
[tex]2x + 100 = 5x + 55 \\ 100 - 55 = 5x - 2x \\ 45 = 3x \\ \frac{3x}{3} = \frac{45}{3} \\ x = 15[/tex]
so,2(15)+100=130
