Question

solve the following equations. y-1 upon 4 - y-2 upon 3 = 1 ​

Answer 1

$\huge\mathfrak\red{Solution}$

$\frac{y - 1}{4} - \frac{y - 2 }{3} = 1 \\ \\ \frac{3(y - 1) - 4(y - 2)}{12} = 1\\ \\ \frac{3y - 3 - 4y + 8}{12} =1\\ \\ \frac{- y + 5}{12} = 1 \\ \\ 12 = -y + 5 \\ \\ 12 - 5 = -y \\ \\ 7 = -y \\ \\ y = -7$
