Answer:
12
Step-by-step explanation:
I assume you are trying to solve for each variable. if thats the case you want to use one equation to solve for y and then plug the y value into the next variable
Problem: y =-3x=4 so -3x+4=3x-2
x=1
plug x value into one of the equations
y=3(1)-2
y=1
31 is 25x3+8x3=51 because you multiply each of the numbers for it to equal 51
