Write whether the following statement is True or False? Justify your answer.
The coordinates of points given in the table :
$\begin{array}{|c|c|c|c|c|c|} \hline x & 0 & 1 & 2 & 3 & 4 \\ \hline y & 2 & 4 & 6 & 8 & 10 \\ \hline \end{array}$
represent some of the solutions of the equation $2 x+2=y$
Express the equation $2 x+3 y=12$ in the standard form and find the value of $a+b+c$
How many linear equations in $x$ and $y$ can be satisfied by $x =1$ and $y =2 ?$
For equation $3 x-2 y=12, y=\ldots \ldots \ldots$
If $(5,2)$ is a solution of the equation $k x+4 y=33,$ find the value of $k$
