Question

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

Answer 1

(-2y+1) + 3 y = -2

y + 1 = -2

y = -3

x = -2(-3) + 1

x = 7

Answer 2

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

Answer 3

2y/3+27+3y/4=-24
