Solve the system of equations below using the Equal Values Method. Homework Help ✎

a = 12b + 3
a = −2b − 4

Set the two equations equal to each other.

Solve for b.

12b + 3 = −2b − 4

14b = −7

Substitute b back into one of the original equations to find a.

Remember to check by substituting a and b back into both of the original equations.

a = −6 + 3

a = −3
