Assuming you want to solve for x:

Make 15x and 15 add up to 180 in an equation since they form a straight line. A straight line is 180 degrees.

15x + 15 = 180

Subtract 15 from both sides.

15x = 165

Divide both sides by 15.

x = 11

15 + 15 + 15x + 15x = 180

30 + 30x = 180

30x = 150

x = 5

Given the equation 7(x + 2) = 2x − 1, solve for the variable. Explain each step and justify your process. Jeff solved a similar

Galina-37 [17]

You have to distribute the 7 to x and 2 so :
7x+14=2x-1
Add one to both sides (inverse operations)
7x+14=2x-1
+1 +1
7x+15=2x
Cross Cancel by subtracting 7x from both sides
7x+15=2x
-7x -7x
15=-5x
Divide by -5
15/-5= -5/-5
X= -3
