Answer:
Part A: S= 24x-72
Part B: S and T are not equivalent for any values of x since when both equations are set equal to 0 they equal different answers. T=.75, while S=3
Step-by-step explanation:
To distribute first you multiply 4 by 6x which equals 24, then you multiply 4 by -18 which gives you -72. Then you the equation together.
10x-12 is the answer I believe

Step-by-step explanation: Confounding variables are
