Question

If 2x + 1 = 4, then x + 2 =

Answer 1

3 1/2 or 3.5

Explanation:

2x+1=4

-1 -1

2x=3

divide by 2 to isolate the x

x= 3/2 or 1 1/2

so then,

1 1/2 + 2 = 3 1/2 or 3.5

Answer 2

x+2 = 3.5

Explanation:

2x + 1 = 4

Subtract 1 from each side

2x + 1-1 = 4-1

2x = 3

Divide by 2

2x/2 = 3/2

x = 1.5

We want to find x+2

1.5+2

3.5

x+2 = 3.5
