Question

500x+6y=11216. and 800x+4y=9344 solve substuition method

Answer 1

we have

$500x+6y=11,216$ ---------> equation $1$

$800x+4y=9,344$ ---------> equation $2$

In the equation $1$ clear variable x

$500x+6y=11,216\\ 500x=11,216-6y$

$x=22.432 -0.012y$ ----------> equation $3$

Substitute the equation $3$ in the equation $2$

$800*[22.432 -0.012y]+4y=9344$

$800*[22.432 -0.012y]+4y=9,344\\17,945.6- 9.6y+4y=9,344\\9.6y-4y= 17,945.6-9,344\\ 5.6y=8,601.6\\y=8,601.6/5.6\\y= 1,536$

Find the value of x

$x=22.432 -0.012y$

$x=22.432 -0.012*1,536$

$x=4$

therefore

the answer is

$x=4$

$y=1,536$
