Question

8x-19y=2550
7x-16y=2550
Solve by elimination method class 10

Answer 1

$\text{Given equations are}$

$8x-19y=2550$......(1)

$7x-16y=2550$......(2)

$\text{Adding (1) and (2), we get}$

$15x-35y=5100$

$3x-7y=1020$.......(3)

$\text{Subtract (2) from (1), we get}$

$x-3y=0$.........(4)

$\text{Multiply by 3 }$

$3x-9y=0$

$3x-7y=1020$.......(3)

$\text{Subtracting, we get}$

$-2y=-1020$

$\bf\;y=510$

$\text{put y=510 in (4), we get}$

$x-3(510)=0$

$\bf\;x=1530$

$\therefore\textbf{The solution is x=1530 and y=510}$
