Question

(2x+3,2+y)=(y+4,3x+2) find the value of x and ​

Answer 1

x = -1

y = -3

Explanation:

`\begin{cases}2x+3=y+4\\ 2+y=3x+2\end{cases}`

`\Longleftrightarrow \begin{cases}2x-y=1&\left( 1\right) \\ 3x-y=0&(2)\end{cases}`

(2) - (1) ⇒ (3x - y) - (2x - y) = 0 - 1 ⇒ x = -1

(1) ⇒ 2x - y = 1 ⇒ y = 2x - 1 = 2(-1) - 1 = -3
