Sagot :
Answer:
x = -1
y = -2
Step-by-step explanation:
To get y by itself:
3x - y = -1
-y = -1 - 3x
y = 1 + 3x
Solve for x with substitution:
2x = 4(1 + 3x) + 6
2x = 4 + 12x + 6
2x = 10 + 12x
-10x = 10
x = -1
Plug the x value into 3x - y = -1
3(-1) - y = -1
-3 - y = -1
-y = 2
y = -2
Answer:
x = -1 and y = -2
Step-by-step explanation:
2x = 4y +6
x = 2y + 3
3(2y+3) - y = -1
6y+9 - y = -1
6y - y = -10
5y = -10
y = -2
2x = 4(-2) + 6
2x = -8 + 6
x = -4 + 3
x = -1
