solve: 2x+2(x+3)=2(x+7)

what I got was x=4 but I really think I calculated wrong. Can you show me the step by step process please?

first off, did you check to see whether x=4 fits the equation?

2(4)+2(4+3) =?= 2(4+7)
8 + 14 =?= 22
yes, so your answer is correct

2x+2(x+3)=2(x+7)
2x+2x+6 = 2x+14
4x+6 = 2x+14
2x = 8
x = 4

Looks like you nailed it.
Good job.
2x+2(x+3)=2(x+7)

2x + 2x + 6 = 2x + 14

4x + 6 = 2x + 14

2x = 8

x = 4

You're right.
