Answer:

does this help

Step-by-step explanation:

Simplifying

6x + -7 = 180

Reorder the terms:

-7 + 6x = 180

Solving

-7 + 6x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '7' to each side of the equation.

-7 + 7 + 6x = 180 + 7

Combine like terms: -7 + 7 = 0

0 + 6x = 180 + 7

6x = 180 + 7

Combine like terms: 180 + 7 = 187

6x = 187

Divide each side by '6'.

x = 31.16666667

Simplifying

x = 31.16666667
