Question

3(5x+1)-3x=2-3(3x+1)

Answer 1

x=
`-(4)/(21)`

Explanation:

Step 1- Distribute into the parenthesis.

(3)5x+(3)1-3x=2+(-3)3x+(-3)1

Step 2- Multiply.

15x+3-3x= 2-9x-3

Step 3- Add common variables.

(15x-3x)+3=(2-3)-9x

12x+3=-1-9x

Step 4- Add 9x to both sides.

12x+3= -1-9x

+9x +9x

21x+3= -1

Step 5- Subtract 3 to both sides.

21x+3= -1

-3 -3

21x= -4

Step 6- Divide both sides by 21.

21x= -4

21 21

x=
`-(4)/(21)`
