Y=4x<br> x+y=5 use substitution method
dalvyx [7]

Answer:

x = 1, y = 4

Step-by-step explanation:

y = 4x

x + y = 5

Since 4x is equal to the variable y, we can substitute it in for y in the second equation.

x + (4x) = 5

Solve for x.

x + 4x = 5

5x = 5

5x/5 = 5/5

x = 1

Now that we have solved for x, we need to solve for y.

y = 4x

x = 1 so substitute the x with 1.

y = 4(1)

y = 4

We can plug both of our answers into any one of the given equations to check our work

x + y = 5

x = 4 and y = 1

4 + 1 = 5

5 = 5
