Question:
Solve the following systems of equations:
$7(y+3)-2(x+2)=14$
$4(y-2)+3(x-3)=2$
Solution:
The given equations are:
$7(y+3)-2(x+2)=14$ $\ldots(i)$
$7 y-2 x=-3$
$4(y-2)+3(x-3)=2$ $\ldots(i i)$
$4 y+3 x=19$
Multiply equation $(i)$ by 3 and equation $(i i)$ by 2 and add both equations we get
Put the value of $x$ in equation $(i)$ we get
$7 \times 1-2 x=-3$
$\Rightarrow-2 x=-10$
$\Rightarrow x=5$
Hence the value of $x=5$ and $y=1$
