Solve each system using substitution. check your solution.
a = 2/3b -3
a = 2b - 18
c = 3d -27
4d + 10c = 120
Ah, sometimes we do not see a question immediately. Also I am wondering what you have done so far yourself.
to find d you have to plug c = 3d -27 into 4d + 10c = 120. then maybe to find a you have to make 2/3b -3 =2b - 18. Not sure if that's right.
Sure Miley, those will work. However I told him that when he posted them earlier.
