Question

How do you solve this
3(2.6x-3=4(-7-2.8)

Answer 1

`x=-3.87`

Explanation:

We want to solve for
`x` in
`3(2.6x-3)=4(-7-2.8)`

We expand to get:
`7.8x-9=-28-11.2`

We group similar terms to get:

`7.8x=9-28-11.2`

This simplifies to
`7.8x=-30.2`

Divide both sides by 7.8 to get

`x=(-30.2)/(7.8)= -3.8718`
