Question

Solve the system by the substitution method.X-6y = 63x - 18y = 7

Answer 1

X-6y = 6

3x - 18y = 7

Isolate x in the first equation:

x=6+6y

Substitute the value of x in the second equation:

3(6+6y)-18y=7

Solve for y:

3(6)+3(6y)-18y=7

18+18y-18y =7

18=7

Since 18 is not equal to 7, the system has no solutions (Ø).
