The equation below shows the area of a trapezoid, A, with a height of 9 cm, and one base 35 cm.

A = 9 over 2(b + 35)

Which of the following formulas correctly solves for the other base, b?

b = 2A over 9 + 35

b = 2 multiplied by A over 9 − 35

b = 2 multiplied by A plus 35, all over 9

b = 2 multiplied by A minus 35, all over 9
I'm having a tough time with this one someone help me please

1. A = 9/2 (b+35)
2A/9 = b+35
2A/9 - 35 = b
