16 - 6 x 2 = 20

16 - 6 x 2 = 4

200

20 ÷ 5 x 2 = 2

20 ÷ 5 x 2 = 8

300

5 x 5 +1 = 30

5 x 5 + 1= 26

400

5 + 7 - 3 x 2 = 18

5 + 7 - 3 x 2 = 6

500

The problem was 30 - 5 x 2 + 3. My answer was 53. What did I do wrong?

I did not multiply first. The answer should be 23.

Mixed Review

100

Solve for x

9 + x = 15 

x = 6

200

Solve for Y

Y x 4 = 20

Y = 5

300

8  x 6 + x = 55

x = 7

400

4 x 8 - y = 27

y = 5

500

(5 x 4) + (Y x 3) = 26

Y = 6
