Question

Equations with fractions; Show work!
-7x + 3 = -15/2

Answer 1

you can start by subtracting 3 from both sides, so you'll end up with:

-7x = -15/2 - 3

what is -15/2 - 3?

Answer 2

I got a decimal!

Answer 3

what is it as a fraction?

Answer 4

I don't know how to convert them!

Answer 5

so we have -15/2 and -3
-3 can be written as -3/1
so we have -15/2 - 3/1

however, in order to add/subtract fractions, they need to have a common denominator (bottom part of the fraction)

. so, what do we need to do to 1 to make it become 2? (hint think multiplication)
