four less than the product of a number and 7 is eight more than that number

Answer 1

Hi, Scarlet,

four less than means subtract 4

the product of means what you get when you multiply

a number the amount we don't know, x

and 7 you will multiply by 7

is means equals

eight more than means add 8

that number the same amount we don't know, x

Putting the above together into an equation, we get:

7x - 4 = 8 + x

Subtract 1x from both sides:

6x - 4 = 8

Add 4 to both sides:

6x = 12

Divide both sides by 6:

x = 2

I hope this helps!

Best, Karen
