Hey there!
4x - 2y = 8
4x - 2(-2) = 8
4x + 2(2) = 8
4x + 4 = 8
SUBTRACT 4 to BOTH SIDES
4x + 4 - 4 = 8 - 4
CANCEL out: 4 - 4 because it give you 0
KEEP: 8 - 4 because it help solve for the x-value
NEW EQUATION: 4x = 8 - 4
SIMPLIFY IT!
4x = 4
DIVIDE 4 to BOTH SIDES
4x/4 = 4/4
CANCEL out: 4/4 (the LEFT side) because it give you 1
KEEP: 4/4 (the RIGHT side) because it gives you the value of x.
NEW EQUATION: x = 4/4
SIMPLIFY IT!
x = 1
Therefore, your answer should be:
x = 1
And possibly y = -2
Good luck on your assignment & enjoy your day!
