Question

2(x + 6) − (x + 1) = 16

Answer 1

Expand the values first
2(x+6)-(x+1)=2x+12-x-1=x+11
so x+11=16
then x=5

Answer 2

Distribute first. If you know how to.

Answer 3

2(x+6) becomes 2x+12

-(x+1) becomes -1(x+1) which becomes -x-1

Put it together to get 2x+12-x-1
Combine like terms:
2x-x
12-1
to get x+11

x+11=16

Solve for x.
