(-2y+1) + 3 y = -2
y + 1 = -2
y = -3
x = -2(-3) + 1
x = 7
x=-2y+1
x+3y=-2
Please help me solve each system of equations and show your work thanks.

perfectly set up for using substitution
sub the 1st into the 2nd
x + 3y = -2
(-2y+1) + 3y = -2
-2y + 1 + 3y + -2
y = -3
back into the 1st: x = -2(-3)+1 = 7
x = 7 , y = -3
sub the 1st into the 2nd
x + 3y = -2
(-2y+1) + 3y = -2
-2y + 1 + 3y + -2
y = -3
back into the 1st: x = -2(-3)+1 = 7
x = 7 , y = -3
2y/3+27+3y/4=-24
