Estimate the difference. 9 1/2 - 1 6/7

8 1/2
8
7
7 1/2

Step-by-step explanation:

9 - 1 Let put this aside

1/2 - 6/7 is 7 x 2 = 14

So 7/14 - 12/14 = 5/14

Now 9 - 1 = 8 Soo...

x = 6

Step-by-step explanation:

First step is to distribute the 5(x + 2).

5x + 10 = 6x + 3x - 14

The 6x and the 3x on the right can be combined.

5x + 10 = 9x - 14

Now add 14 to both sides to isolate the 9x.

5x + 24 = 9x

Subtract 5x from both sides.

24 = 4x

Divide by 4 to get x by itself.

6 = x
