Answer :

Step-by-step explanation:

Simplifying

3x + -28 + 3x + -30 + x = 33

Reorder the terms:

-28 + -30 + 3x + 3x + x = 33

Combine like terms: -28 + -30 = -58

-58 + 3x + 3x + x = 33

Combine like terms: 3x + 3x = 6x

-58 + 6x + x = 33

Combine like terms: 6x + x = 7x

-58 + 7x = 33

Solving for variable 'x'.

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

Add '58' to each side of the equation.

-58 + 58 + 7x = 33 + 58

Combine like terms: -58 + 58 = 0

0 + 7x = 33 + 58

7x = 33 + 58

Combine like terms: 33 + 58 = 91

7x = 91

Divide each side by '7'.

x = 13

Simplifying

x = 13

AnswerSolving

-58 + 7x = 33
