Question

SO CLOSE! A system of two equations is shown below:

Equation C: a = 3b + 6
Equation D: a = 7b − 1

What value of a can be substituted into equation D to solve the system of equations?
3b
7b
3b + 6
7b − 1

Answer 1

3b+6

If you make both equations equal each other, you can then solve the system of equations.

Answer 2
