If you would like to solve the equation 2x / 5 + 1 = 7, you can do this using the following steps:
2x / 5 + 1 = 7
2x + 5 = 5 * 7
2x = 35 - 5
2x = 30
x = 15
If you would like to solve the equation x/3 - 4 = 10, you can do this using the following steps:
x/3 - 4 = 10
x/3 = 10 + 4
x/3 = 14
x = 14 * 3 = 42
