Answer:
(1, 1)
Explanation;
Given the simultaneous equation:
y = -2x + 3 ..... 1
2x + 2y = 4 ...... 2
Substitute equation 1 into 2;
2x+2y = 4
2x+2(-2x+3) = 4
Expand
2x-4x+6 = 4
-2x + 6 = 4
-2x = 4 - 6
-2x = -2
Divide both sides by -2
-2x/-2 = -2/-2
x = 1
Substituting x = 1 into equation 1;
From 1:
y = -2x + 3
y = -2(1) + 3
y = -2 + 3
y = 1
Hence the solution to the system of equation is (1, 1)
