Question

Substitution
6x+2y=0
4x+y=-1

Answer 1

do you need the process or the answer or both?

Answer 2

both

Answer 3

4x + y = -1
y = -4x - 1
now sub -4x - 1 in for y in the other equation

6x + 2y = 0
6x + 2(-4x - 1) = 0
6x - 8x - 2 = 0
6x - 8x = 2
-2x = 2
x = -1

now sub -1 in for x in either of the equations to find y
4x + y = -1
4(-1) + y = -1
-4 + y = -1
y = -1 + 4
y = 3

check..
6x + 2y = 0
6(-1) + 2(3) = 0
-6 + 6 = 0
0 = 0 (correct)

solution is : (-1,3)
