Question

Solve this equation.
13(y+7)=3(y−1).​

Answer 1

Answer:

7x + 13y = 27 ....(i) 13x + 7y = 33 ....(ii) Multiplying by 13 and 7 in equation (i) and (ii) respectively, we get 91x + 169y = 351 -91x -+49y = -231 120y ..

Answer 2

${\huge{\underline{\boxed{\red{\mathcal{Answer}}}}}}$

$\implies \text{13(y+7) = 3(y-1)} \\ \implies \text{13y + 91 = 3y - 3} \\ \implies \text{13y - 3y = -3 - 91} \\ \implies \text{10y= -94} \\ \implies \text{ y = \dfrac{-94}{10} } \\ \implies \textbf{y = -9.4} \\ \text{HOPE IT HELPS!!!!!}$
