Question

Solve for a. 7a-2b=5a+b

Answer 1

a = 3/2b

Explanation:

7a - 2b = 5a + b

+2b + 2b

7a = 5a + 3b

-5a -5a

2a = 3b

/2 /2

a = 3/2b

Answer 2

8.5b.
7a= 5a +3b
-5a -5a
2a = 3b
/2
a= 1.5b
Solve by substitution and you get;
8.5b=8.5b
Because of the lack of constants in the equation there isn't a definite answer.
