x = 4, y = - 5 OR (4, - 5)
Step-by-step explanation:
Step 1: Solve for y in the first equation
2x + y - 2x = 3 - 2x
y = 3 - 2x
Step 2: Plug in that into the second equation to get x
4x + 3 (3 - 2x) = 1
4x + 9 - 6x = 1
-2x + 9 - 9 = 1 - 9
-2x / - 2 = - 8 / - 2
x = 4
Step 3: Use x to find y
y = 3 - 2 (4)
y = 3 - 8
y = - 5
Answer: x = 4, y = - 5 OR (4, - 5)
