Question

Three times the difference of a number and 7 is 2

Answer 1

3(x-7)=2
basically we break it up into parts
three times is multiplication
3*
so we are multiplying 3 and the difference of a number and 7
difference equals subtraction so we now we are subtracting 7 from a number and then multiplying the difference
so since we don't have a given number to subtract from 7 we put a variable i'm going to use x as the variable
so we have 7-x and we have to multiply it by three
3(7-x)
we use parentheses so when we do the problem we know to do the subtraction first then multiply it all by three
then finnally the problem say that 3(7-x) is going to be 2 so the equation is
3(7-x)=2 (three times the difference of seven minus a number is two)

Answer 2

/3*/= three times
/7-x/ = seven minus a number
/=2/ = is two
