Question

13(y-4) -3(y-9) = 5(y+4) solve and check
​

Answer 1

Answer:

The valve of y=9

Step-by-step explanation:

13(y-4)-3(y-9)=5(y+4)

$13(y - 4) - 3(y - 9) = 5(y + 4) \\ \\ 13y - 52 - 3y + 27 = 5y + 20 \\ \\ 10y - 25 = 5y + 20 \\ \\ 10 y - 5y = 20 + 25$

$5y = 45 \\ y = 45 \5 \\ \\ y = 9$

checking :-

LHS,

13(y-4)-3(y-9) putting value of y=9

13(9-4)-3(9-9)

$13 \times 5 = 65$

Now, RHS,

$5(y + 4) \\ putting \: valve \: of \: y = 9 \\ \\ 5(9 + 4) = 5 \times 13 \\ = 65 = lhs$
