solve for y 6y+3 (y-6)=5 (y+1)-2

Question

Trying to help my kid

Answer 1

 6y+3 (y-6)=5 (y+1)-2 

6y+3y-18 = 5y+5-2   

9y-18=5y+3                

9y-5y-18=3             

4y-18=3                   

4y=21                          

y=5,25                       

 

Answer 2

Question: solve for y: 6y+3 (y-6)=5 (y+1)-2 .

6y + 3(y - 6) = 5(y + 1) - 2   -- expand the brackets

6y + 3y - 18 = 5y + 5 - 2     -- put all the y-terms on one sides, and the numbers on the other.

6y + 3y - 5y = 5 - 2 + 18     -- now do some arithmetic

4y = 21

y = 21/4
