Question

12 less that 6 times a number

Answer 1

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

y-(12-6*x)=0

Answer 2

6x-12

you don't know what the 'number' is so put it as a letter like 'x'

12 is getting subtracted from 6(x)

so 6x-12
