Step-by-step explanation:
<u>Step 1: Define Equation</u>
3.5(x + 12) = -2x + 18
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 3.5: 3.5x + 42 = -2x + 18
- Add 2x on both sides: 5.5x + 42 = 18
- Isolate <em>x</em> term: 5.5x = -24
- Isolate <em>x</em>: x = -4.36364
X=11
<span>Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation.</span>
X = ?, y = ?;
2 x - 70° = x + 30°
2 x - x = 30° + 70°
x = 100°
x + 30° + 5 y = 180°
130° + 5 y = 180°
5 y = 180° - 130°
5 y = 50°
y = 50° : 5
y = 10°
Answer: C ) x = 100, y = 10
