Solve using the substitution method. Show your work. If the system has no solution or an infinite number of solutions, state this.

3x – 15y = -12

3x + 24y = -12

Rather than substitution, why don't we just subtract them as they stand.

-29y = 0

y = 0

then 3x = -12

x = -4

If you really have to use substitution,

form the first , 3x = 15y - 12

into the 2nd

15y - 12 + 24y = -12

29y = 0

then 3x = 15(0) - 12

3x = -12

x = -4
