Find the value of the variable in each equation. Please put a solution.
1) 4a - 4 = 40
2) 9m + 7 = 34
3) 8n + 3 = 75
4) 5x / 3 = 20
5) 30 / y = 3
6) 27 = 7 + 7w - 2w
7) b / 8 + 5 = 12
8) 4c / 2 = 36
9) 4p - 10 = 2p + 50
10) 7e / 8 - 9 = 5
*The slash(/) is for division*

27 + 34
3. 9
8(9) + 3 = 75
72 + 3 = 75
4. 12
5(12) / 3 = 20
60 / 3 = 20
5. 10
30 / 10 = 3
