15(y-4)-2(y-9)+5(y+6)=0

Question

this is a questation on maths of linear equation is one variable

Answer 1

first you should simplify the expression

 

15(y-4) -2(y-9) +5(y+6) = 0

 

15y -60 -2y+18 +5y+30 =0

 

then combine like terms

 

(15-2+5)y +(-60+18+30) = 0

 

18y -12=0

 

then isolate y

 

18y=12

y=12/18

 

simplify

 

y=2/3
