Question

How do you solve `\frac { 3} { 5} ( 15x + 10) = - 3`?

Answer 1

`x=-1`

Explanation:

Multiplying by `5` we get

`3(15x+10)=-15`
expanding

`45x+30=-15`
so
45x=-45x=-1#

Answer 2

`x=-1`

Explanation:

`"multiply both sides by 5 to eliminate the fraction"`

`cancel(5)xx3/cancel(5)(15x+10)=5xx-3`

`3(15x+10)=-15larrcolor(blue)"distribute"`

`45x+30=-15`

`"subtract 30 from both sides"`

`45x=-15-30=-45`

`"divide both sides by 45"`

`x=(-45)/45=-1`
