Question

pls solve this please

Answer 1

here
5(y-8)= 3(y-4)
5y -40 = 3y -12
5y-3y = -12+40
2y = 28
y=14

Answer 2

Given Equation : $\dfrac{y-8}{3}=\dfrac{y-4}{5}$


Now,
As the product of 5 and 3 is 15, multiply by 15 on both sides of the equation.


$\implies \dfrac{y - 8}{3} \times 15 = \dfrac{ y- 4}{5} \times 15 \\ \\ \\ \implies ( y - 8) \times 5 = (y - 4) \times 3 \\ \\ \implies 5y - 40 = 3y - 12 \\ \\ \implies 5y - 3y = 40 - 12 \\ \\ \implies 2y = 28 \\ \\ \implies y = \dfrac{28}{2} \\ \\ \implies y = 14$


Therefore the numeric value of y is 14 which is satisfying the given equation.
