Question

2(x+1)+3=7 how do I solve this? Is this correct? 2(x+1)+3=7 2x + 2 +3=7 2x+2 +3=7 2x+5=7    -5     7 2x=  2 2       2  x=1

Answer 1

Yes, that's correct.

Here's another way to approach it:

                                          2 (x + 1) + 3 = 7

Subtract  3  from each side:    2 (x + 1) = 4

Divide each side by  2 :                x + 1 = 2

Subtract  1  from each side:              x  =  1



                    

Answer 2

You betcha! Your work is correct! Here is a little different way to solve it. So you can choose which one is simpler for you!

2(x+1)+3=7

Simplify both sides of the equation.

2(x+1)+3=7

Simplify

2x+5=7

Subtract 5 from both sides.

2x+5−5=7−5

2x=2

Divide both sides by 2.

2x / 2=2 / 2

x=1
