Question

I have to solve the system of linear equations by elimination. i also have to check my solution.

Answer 1

Answer:

$x=1$, $y=6$

Step-by-step explanation:

Give.

$x+2y=13$----------(1)

$-x+y=5$------------(2)

Solve this linear equation by elimination method.

Add equation 1 and 2

$x+2y=13$

$-x+y=5$

-----------------------------

$0+3y=18$

$3y=18$

$y=\frac{18}{3} \\y=6$

Put y value in equation 2

$-x+6=5$

$-x=5-6$

$-x=-1$

$x=1$

$x=1$, $y=6$
