If you would like to know what value of a can be substituted into equation a = 5b - 3 to solve the system of equations, you can do this using the following steps:

equation c: a = 2b + 7
equation d: a = 5b - 3
__________________
a = 5b - 3
2b + 7 = 5b - 3
7 + 3 = 5b - 2b
10 = 3b
b = 10/3

The correct result would be 2b + 7.
