Question

(-300):20+5.(3x-1)=25

Answer 1

(-300):20+5.(3x-1)=25`

`-15+5.(3x-1)=25`

`5.(3x-1)=25+15=40`

`3x-1=40:5=8`

`3x=8+1=9`

`x=9:3=3`

Answer 2

`(-300):20+5.(3x-1)=25`

`=>-15+15x-5=25`

`=>15x-20=25`

`=>15x=25+20=45`

`=>x=45/15=3`

Answer 3

`-15 + 15x - 5 = 25`

`15x = 45`

`x = 45/15`

`x = 3`
