Question

find х x the value of for the equations aty: 5 and x-y=1​

Answer 1

Answer:

Heya❤

\begin{gathered}x + y = 5 \: \: \: ...(1) \\ x - y = 1 \\ x =1 + y \: \: ..(2) \\ \\ substitute \: equation \: 2 \: in \: equation \: 1 \\ \\ (1 + y) + y = 5 \\ 1 + 2y = 5 \\ 2y = 4 \\ y = 2 \\ \\ substitute \: the \: value \: of \: y \: in \: eq \: 2 \\ \\ \: x = 1 + 2 \\ x = 3\end{gathered}

x+y=5...(1)

x−y=1

x=1+y..(2)

(1+y)+y=5

1+2y=5

2y=4

y=2

x=1+2

x=3
