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.

2 +2

Sure Miley, those will work. However I told him that when he posted them earlier.
