Answer:
(8, -22) All real numbers
Step-by-step explanation:
So since we already have the value of y lets Substitute;
3x + (-4x + 10) = 2
Distribute;
3x - 4x + 10 = 2
Collect like terms;
-1x + 10 = 2
Subtract 10 from both sides;
-1x = -8
Divide both sides by -1
x = 8
So now lets get the actual value for y by substituting x;
y = -4(8) + 10
y = -32 + 10
y = -22
(x, y) = (8, -22)
