Question

9y + 5 = 15y – 1 Solve the equation

Answer 1

[tex]9y+5=15y-1\\ 5+1=15y-9y\\ 6=6y\\ y=1[/tex]

Answer 2

answer : 1

explanation : given equation is , 9y + 5 = 15y - 1

subtract 9y from both sides so you remove the variable term on the left hand side.

or, 9y + 5 - 9y = 15y - 1 - 9y

or, 9y - 9y + 5 = 15y - 9y - 1

or, 0 + 5 = 6y - 1

or, 5 = 6y - 1

add 1 to both sides so you remove the constant term on the right hand side.

or, 5 + 1 = 6y - 1 + 1

or, 6 = 6y

or, 6/6 = 6y/6 = (6/6)y

or, 1 = 1y

or, y = 1

hence, value of y = 1
