Substitute the 2x+2 for y in the first equation:
-4x - (2x+2) = 4
Distribute that negative:
-4x - 2x - 2 = 4
Combine like terms:
-6x - 2 = 4
Add 2 to both sides:
-6x = 6
Divide by -6:
x = -1
Substitute that -1 into either equation:
y= 2x + 2
y= 2(-1) + 2
y= -2 + 2
y= 0
Answer:
x = -1
y = 0

Step-by-step explanation:
<u>Step 1: Define equation</u>
2.5x + 10 = x - 0.5
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract <em>x </em>on both sides: 1.5x + 10 = -0.5
- Subtract 10 on both sides: 1.5x = -10.5
- Divide both sides by 1.5: x = -7
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 2.5(-7) + 10 = -7 - 0.5
- Multiply: -17.5 + 10 = -7 - 0.5
- Add/Subtract: -7.5 = -7.5
