Question

If 3x + 7 = 14, then x =​

Answer 1

`x = 2.33333333333`

Explanation:

3x + 7 = 14

First step:

Backwards method:

14 - 7 = 7

This means that we somehow need to find a number to fit x into three to get the other 7.

Final step:

7/3 to see our solution

=> 2.33333333333

Check our work:

Plug it in:

( 3 * 2.33333333333) + 7 = 14

7 + 7 = 14

Answer 2

x = 7/3

Explanation:

3x + 7 = 14

Subtract 7 from both sides.

3x = 7

Divide both sides by 3.

x = 7/3
