Answer 1

[Bí Mật]

42 + y/76 = 153/171

 y/76        = 153/171 - 42

y/76          = 781/19

y               = 3124

Answer 2

\(42+\frac{y}{76}=\frac{153}{171}\)

           \(y:76=\frac{153}{171}-42\)

            \(y:76=-\frac{781}{19}\)

                    \(y=-\frac{781}{19}\times76\)

                    \(y=-3124\)
