Question

(-y + 5.3) + (7.2y - 9) = 6.2y +n whats the value of n?

Answer 1

-remove the ( ) -y+5.3 + 7.2 -9 = 6.2Y + n combine like terms 6.2y -3,7 =6.2y +n 6,2 y cancels out -3.7= n

Answer 2

`(-y+5.3)+(7.2y-9)=6.2y+n\\-y+5.3+7.2y-9=6.2y+n\\(-y+7.2y)+(5.3-9)=6.2y+n\\6.2y-3.7=6.2y+n\ \ \ \ |subtract\ 6.2y\ from\ both\ sides\\-3.7=n\\\boxed{n=-3.7}}`
