Answer:
(3,0)
Step-by-step explanation:
2x + 2y = 6 divide thru by 2 and you get x + y = 3
Name x + y = 3 equation (1) and x - y = 3 equation (2)
Add equations (1) and (2)
(1) x+ y = 3
(2) <u> x - y = 3 </u>
2x = 6
x = 3
Substitute x = 3 into equation (1). So, 3 + y = 3
y = 0
-3 1/2 = 1/2x + 1/2x + x
- 7/2 = 2x
(-7/2) / 2 = x
-7/2 * 1/2 = x
- 7/4 (or - 1 3/4) = x
