Question

How do i solve this equation??
​

Answer 1

x = 3 and y = 6 → (3, 6)

Explanation:

`\left\{\begin{array}{ccc}2x-y=0&\text{add y to both sides}\\3x-2y=-3\end{array}\right\\\\\left\{\begin{array}{ccc}2x=y&\to y=2x&(1)\\3x-2y=-3&&(2)\end{array}\right\\\\\\\text{Substitute (1) to (2):}\\\\3x-2(2x)=-3\\3x-4x=-3\\-x=-3\qquad\text{change the signs}\\\boxed{x=3}\\\\\text{Put the value of x to (1)}:\\\\y=2(3)\\\boxed{y=6}`
