Question

Verify (0, 3) is a solution to x+y=3 and y=-X+3.

Answer 1

Given:

`\begin{gathered} x+y=3 \\ y=-x+3 \end{gathered}`

given solution is (0,3)

`\begin{gathered} (0,3) \\ so\text{ the value x=0} \\ y=3 \end{gathered}`

check for sol. put the value in equation then:

`\begin{gathered} x+y=3 \\ x=0,y=3 \\ 0+3=3 \\ 3=3 \end{gathered}`

for another equation :

`\begin{gathered} y=-x+3 \\ x=0,y=3 \\ 3=0+3 \\ 3=3 \end{gathered}`

so the solution of x and y is right.
