Question

Solve 2x - 5 = 7
Need explanation and working out for x?

Answer 1

Move all terms not containing x to the right side of the equation.

Add 5 to both sides of the equation.

2x=7+5

Add 7 and 5.

2x=12

Divide each term by 2 and simplify.

2x/2=12/2

Divide x by 1.

x=12/2 => x=6

Explanation:

Answer 2

12/2=6

Explanation:

You have to do the same thing to each side and try and move all the numbers to one side, leaving x alone so:

2x-5=7

+5:

2x=12

/2:

x=12/2

x=6
