(8x-7) + (x+16)=180
Solve For X

X = 19

Step-by-step 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!!! :)

x = 19

Step-by-step explanation:

Step 1: Define

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

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
