y = 13 - 3x (from the first equation)
Substitute that for y in the second equation, and solve for x.
12x + 54*13 - 162x = -48
150 x = 750
Take it from there.
Solve using the substitution method. Show your work. If the system has no solution or an infinite number of solutions, state this.
18x + 6y = 78
12x + 54y = -48
