Final answer:
To solve for x in the equation (9x + 8) + 7x + 40 = 180, combine like terms, isolate x, and solve .x = 132/16 = 8.25
Step-by-step explanation:
To solve for x in the equation (9x + 8) + 7x + 40 = 180, we need to simplify and combine like terms. First, let's combine the terms with x:
9x + 7x + 8 + 40 = 180
Combining like terms:
16x + 48 = 180
To isolate x, we subtract 48 from both sides:
16x = 132
Finally, we divide both sides by 16 to solve for x:
x = 132/16 = 8.25
