Answer 1

Substitution method means you substitute one variable for the other. So first, we need to isolate one variable.

x+5y=3
-5y on both sides
x = 3 -5y

So now, we'll put the value of x, in the other equation. The value of x is 3-5y.
2(3-5y) +9y = 4
Multiply out the 2

6-10y+9y =4
6-y = 4
Now let's add y to both sides
6=4+y
And subtract 4 from sides.
y=2

Now, we have to use the value of y to get the value of x.
We can do this by plugging in 2 for y in our original x equation.

x=3-(5(2))
x=3-10
x=-7

So the answers are y=2 and x=-7. You can double check this by plugging them in both equations that were originally given.

(-7) + 5(2) = 3
-7+10 = 3
3=3
Which is true
