Answer:

X = 19

Explanation:

You can combine the terms:

(8x-7) + (x+16) = 9x + 9 = 180

Next, you can subtract 9 from both sides:

9x = 171

Next, divide both sides by 9:

X = 19

Hope this Helps!!! :)

Answer:

x = 19

Explanation:

Step 1: Define

(8x - 7) + (x + 16) = 180

Step 2: Solve for x

  1. Combine like terms: 9x + 9 = 180
  2. Subtract 9 on both sides: 9x = 171
  3. Divide both sides by 9: x = 19

Step 3: Check

Plug in x to verify it's a solution.

  1. Substitute: 8(19) - 7 + 19 + 16 = 180
  2. Multiply: 152 - 7 + 19 + 16 = 180
  3. Subtract: 145 + 19 + 16 = 180
  4. Add: 164 + 16 = 180
  5. Add: 180 = 180
