x = 12

Take 6 from x to get y

y = ?

x = 9

Subtract 6 from x, then multiply by 3 to get y

y = ?

x = -3

Multiply x by 2, then add 7 to get y

y = ?

x = 3

Take out 3 times x from 14 to get y

y = ?

x = -2

Multiply x by 5, then add 21 to get y

y = ?

x = 4

24 minus 4 groups of x, then divide the result by 2 to get y

y = ?

x = -7

Take away 8 from x, then divide by 3 to get y

y = ?

x = 4

Subtract 5 from 3 times the number x, then multiply the result by 3 to get y

y = ?

x = 4

Take the square of x, then take out 9 to get y

y = ?

x = 3

Add 7 to the square of x, then divide the result by 2 to get y

y = ?
