Answer 1

Given

`\begin{gathered} Eq1\colon6x+3y=20.25 \\ Eq2\colon8x+3y=25.75 \\ \\ \text{Sum both equations} \end{gathered}`

Procedure

`\begin{gathered} Eq2-Eq1 \\ 8x+3y-6x-3y=25.75-20.25 \\ 8x-6x+3y-3y=5.5 \\ 2x=5.5 \\ x=2.75 \end{gathered}`

Now for y

`\begin{gathered} y=(20.25-6x)/(3) \\ y=(20.25-6\cdot2.75)/(3) \\ y=1.25 \end{gathered}`

The answer would be x = 2.75 and y = 1.25
