To eliminate one of the variables, multiply equation B by 4 and subtract

What are system of equations?

System of equations consists of several equations with unknowns. Given the system of equations

4c = d - 8

4c - d = -8 ............. A

c = 5d +8

c - 5d = 8 ................ B

To eliminate one of the variables, multiply equation B by 4 and subtract

(4c - 4c) + (-d +5d) =-18
4d = -18 (Just one variable)
