Question

Solve for a.

7a - 2b = 5a + b

Answer 1

A=1.5b

Answer 2

I'm sorry not the right answer hold on let me redo the problem

Answer 3

7a - 2b = 5a + b -- subtract 5a from both sides
7a - 5a - 2b = b --- add 2b to both sides
7a - 5a = b + 2b -- simplify
2a = 3b -- divide both sides by 2
a = 3/2b

Answer 4

that should be read as 3b/2

or \[a=\frac{ 3b }{ 2 }\]
