We need to find the value of x and y:

$8x\text{ + 10y = 20}$

First, let solve the x variable:

Subtract 10y on both sides

$8x\text{ +10y -10y = 20-10y}$

$8x\text{ =20-10y}$

Then divide by 8 into both sides :

$(8x)/(8)=\text{ }(20-10y)/(8)$
$x\text{ = }(20-10y)/(8)$

Replace the x value into the first equation:

$8x\text{ + 10y = 20}$
$8((20-10y)/(8))+10y\text{ = 20}$

Now, solve the equation for y:

$20-10y\text{ +10y = 20}$
