would someone write out the whole process of the following question, including solving for y so that i can see what i am doing wrong. Thank you
Solve by the substitution method. write as an ordered pair.
8x3y=94
2x+22=y

8x  3y = 94  Equation 1
2x + 22 = y  Equation 2

Sub y = 2x + 22 in equation 1
8x  3(2x + 22) = 94
8x  6x  66 = 94
2x = 94 + 66
2x = 160
x = 160/2
x = 80
Now sub x = 8 in eq 1 or eq 2 and find for y

Sorry, I made a mistake.
Substitute x = 80 in equation 1 or equation 2 and fine for y.
