Question

​

Answer 1

Simplifying

3x + -7 = 54

Reorder the terms:

-7 + 3x = 54

Solving

-7 + 3x = 54

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 + 3x = 54 + 7

Combine like terms: -7 + 7 = 0

0 + 3x = 54 + 7

3x = 54 + 7

Combine like terms: 54 + 7 = 61

3x = 61

Divide each side by '3'.

x = 20.33333333

Simplifying

x = 20.33333333.
