2x + 4 = 14 (subtract 4 from both sides) 2x = 10 (divide both sides by 2) x = 5
Start with n, then you get; Add 17: n + 17 Double it: 2n + 34 Subtract 4: 2n + 30 Double it: 4n + 60 Add 20: 4n + 80 Divide by 4: n + 20 Subtract 20: n which is where you started.
You get 50.
62 ÷ 13 = 4 with remainder 10 OR 4.76923 times.

4 x (7 - 10/10) = 4 x (7 - 1) = 4 x 6 = 24
(19-4-15)*22*10 = 0
8x + 2 = 6x + 10 Subtract 6x from both sides: 2x + 2 = 10 Subtract 2 from both sides: 2x = 8 Divide by 2: x = 4 x = 4
Add, subtract, multiply, divide.
7 = 4X + 10 subtract 10 from each side -3 = 4X divide both sides by 4 - 3/4 = X check 7 = 4(-3/4) + 10 7 = 7 ( checks )
2x + 4 = 14 (subtract 4 from both sides) 2x = 10 (divide both sides by 2) x = 5
14
