How do you solve the system of equations 2x5y=3 and x3y=1?

1 Answer

Try to get rid of one of the unknown...

Explanation:

2x5y=3
x3y=1 multiply this one by - 2 and add to first one so x term will disappear and we will get an equation with only one unknown parameter which is y

2x5y=3
2x+6y=2
0+y=1y=1
Put 1 instead of y in one of the equations to obtain x
x3(1)=1
x3=1x=4
