Question

4) Solve the following system of equations by graphing. If the system is inconsistent or the
equations are dependent, say so.

30x - 5y = 60
6x = y + 12

Answer 1

The equations are dependent (they're the same equation).

If you multiply the bottom one by 5, you get the top one.

Answer 2

6x X 5= 30x
12 X 5= 60
-5y + (5)= 0=1 (y)
