Answer:
17
Step-by-step explanation:
These two angles add up to 180, so we can set up an equation. 5x-23+7x-1=180. Now we combine like variables, getting 12x-23-1=180. We add 23 to both sides, and get 12x-1=203. Then we add 1 to both sides, getting 12x=204. Finally we divide by 12 on both sides, with our result as x=17.

Step-by-step explanation:
<u>Step 1: Define equation</u>
5x - (x + 4) + 1 = 3 - 2(x + 6)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 5x - x - 4 + 1 = 3 - 2x - 12
- Combine like terms: 4x - 3 = -2x - 9
- Add 2x on both sides: 6x - 3 = -9
- Add 3 to both sides: 6x = -6
- Divide both sides by 6: x = -1
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 5(-1) - (-1 + 4) + 1 = 3 - 2(-1 + 6)
- Parenthesis (Add): 5(-1) - 3 + 1 = 3 - 2(5)
- Multiply: -5 - 3 + 1 = 3 - 10
- Subtract: -8 + 1 = -7
- Add: -7 = -7
