Question

Given the equation 3x + 25 = 7x − 5, which order of operations completely solves for x?

Answer 1

3x+25=7x-5 subtract 25 from both sides

3x=7x-30 subtract 7x from both sides

-4x=-30 divide both sides by -4

x=7.5

Answer 2

x = 7.5.

Explanation:

Given : Given the equation 3x + 25 = 7x − 5,

To find : which order of operations completely solves for x.

Solution : We have given that

3x + 25 = 7x − 5.

Subtracting both side by 3x

25 = 7x - 3x -5.

25 = 4x -5.

On adding both side by 5

25 +5 = 4x .

30 = 4x

on dividing by 4 both side.

x = 7.5.

Therefore, x = 7.5.
