Operation
4 + 6 = 10
Add
x + 100 = 225
Subtraction
4(x + 2) = 16
x = 2
x - 10 = 50
x = 40
5x + 5 = 20
x = 3
10 - 5 = 5
Subtract
x - 50 = 10
2x + 5x + 4 - 2 + 1
7x + 3
x/5 = 5
x = 25
3x - 3 = 9
x = 4
10x = 40
Multiply
x/2 = 12
Multiply
2x(5 + 4) - 10 = 26
x = 2
3x = 27
x = 9
x/4 + 2 = 18
x = 64
3x + 5 = 14
Multiply and Add
3x = 12
Divide
4x + 3xy + 2 + 6x + 7xy - 2
10x + 10xy
x + 14 = 28
x = 14
x/10 + 20 = 100
x = 800
x/14 - 2 = 12
Divide and Subtract
82 + x = 100
Subtracting
10 + 4 - 3x + 2x + 7 + 8y
-x + 8y + 21
2x = 100
x = 50
7x + 2 = 51
x = 7
