Answer:
y = -3
x =
Step-by-step explanation:
4(y + ) - 2y = 8 Distribute the 4. Multiply everything in the parentheses by 4
4y + 14 - 2y = 8 4 = = 14 Combine the like terms 4y and -2y
2y + 14 = 8 Subtract 14 from both sides
2y = -6 Divide both sides by 2
y = -3
Plug -3 in for y in either original equation.
4x - 2y = 8
4x -2(-3) = 8
4x + 6 = 8 Subtract 6 from both sides
4x = 2 Divide both sides by 4
x = =
Check:
x = y +
= -3+
= +
=
4x - 2y = 8
4() - 2(-3) = 8
2 + 6 = 8
8 = 8
