Question

`-4(3x+1)+x-3=15`

Answer 1

`-4(3x+1)+x-3=15`

start using the method PEMDAS

(parenthesis, exponents, multiplication, division, addition, subtraction)

so,

start with multiplying since its the third option to start with

`-12x-4+x-3=15`

now add like variables

`-11x-7=15\\`

continue by changing the signs to the other side +7 on both sides

`-11x=22`

now divide 11 on both sides

`(22)/(-11)` equals to negative 2

Answer :
`-2`

Hope this helps~

Answer 2

`x = - 2`is the answer

Step-by-step explanation -

`-4(3x+1)+x-3=15`

`= > - 12x - 4 + x - 3 = 15`

`= > - 11x - 7 = 15`

`= > - 11x = 15 + 7`

`- 11x = 22`
`= > x = - (22)/(11)`

`= > x = - 2`
