Find an ordered pair (x, y) that is a solution to the equation.-x+3y=2

Sagot :

Solution: (-2,0)

We have an ordered pair. As you can see the equation is:

-x+3y=2

So, we can replace a value of X or Y, in order to get the value of the other variable. For example, if we replace Y=0, we would have:

-x+3(0)=2

-x+0=2

-x=2, we multiply both sides to -1

(-1)*(-x)= 2*(-1)

x =-2 . In that case, we would have the ordered pair (-2,0)
