Solve for x<br> And show work
klemol [59]

Answer:

x = -8

Step-by-step explanation:

1. Because the line the angles x + 96 and 100 + x are on is straight, it's a straight angle that results in 180°.

2. Given the above information, that means x + 96 + 100 + x = 180.

3. (Solving for equation above)

Step 1: Simplify both sides of the equation.

  • (x+x) + (96+100)=180
  • 2x + 196 = 180

Step 2: Subtract 196 from both sides.

  • 2x + 196 - 196 = 180 - 196
  • 2x = -16

Step 3: Divide both sides by 2.

  • \frac{2x}{2} = \frac{-16}{2}
  • x = -8

Step 4: Check if solution is correct.

  • -8 + 96 + 100 - 8 = 180
  • 88 + 100 - 8 = 180
  • 188-8=180
  • 180=180

Therefore, x = -8.
