Answer:
x = 11
Step-by-step explanation:
1. Because this is a straight angle, (11x + 7)° and (5x - 3)° add up to 180°.
- [tex]11x+7+5x-3=180[/tex]
2. (Solving)
Step 1: Simplify both sides of the equation.
- [tex](11x+5x) + (7-3) = 180[/tex]
- [tex]16x + 4 = 180[/tex]
Step 2: Subtract 4 from both sides.
- [tex]16x + 4 - 4 = 180 - 4[/tex]
- [tex]16x = 176[/tex]
Step 3: Divide both sides by 16.
- [tex]\frac{16x}{16} = \frac{176}{16}[/tex]
- [tex]x = 11[/tex]
Therefore, x = 11! I hope this helped you.
