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

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

Answer 2

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
