Question

Find the value of each variable

Answer 1

Answer:

x = 11

Step-by-step explanation:

1. Because this is a straight angle, (11x + 7)° and (5x - 3)° add up to 180°.

• $11x+7+5x-3=180$

2. (Solving)

Step 1: Simplify both sides of the equation.

• $(11x+5x) + (7-3) = 180$
• $16x + 4 = 180$  

Step 2: Subtract 4 from both sides.

• $16x + 4 - 4 = 180 - 4$
• $16x = 176$

Step 3: Divide both sides by 16.

• $\frac{16x}{16} = \frac{176}{16}$
• $x = 11$

Therefore, x = 11! I hope this helped you.
