Question

Answer using elimination will mark brainist -4x+3y=-5 4x-5y=3 2x+3y=36 10x-6y=12

Answer 1

Answer:

Step-by-step explanation:

For Case -1

$\Rightarrow -4x+3y=-5\quad \ldots(i)$

$\Rightarrow 4x-5y=3$

$\Rightarrow 4x=5y+3$

Put the value of $4x$ in equation $(i)$ we get

$\Rightarrow -(5y+3)+3y=-5$

$\Rightarrow -5y+3y-3=-5$

$\Rightarrow 2=2y$

$\Rightarrow y=1$

and thus $4x=5(1)+3$

$x=\frac{8}{4}=2$

Case-2

$10x-6y=12\quad \ldots(i)$

$2x+3y=12\quad \ldots(ii)$

Now multiply $(ii) by 5 and subtract it from (i)$

$10x-6y=12$

$10x+15y=+180$

$\cdots \cdots \cdots$

$-21y=-168$

$y=8$

and $=6$
