Y+2x=4 2y+4x=8 how many soluations

Infinite Solutions

Step-by-step explanation:

We have a system of equation and are asked to determine how many solutions there are.

y + 2x = 4

2y + 4x = 8

To solve, we can first get y by itself in the first equation.

y + 2x = 4

Subtract 2x from both sides :

y = 4 - 2x

Now that y is alone, we can plug it into the second equation :

2(4 - 2x) + 2x = 8

Distribute :

(2(4) - 2(2x)) + 2x = 8

8 - 4x + 2x = 8

Add like terms :

-4x + 2x

8 - 2x = 8

Subtract 8 from both sides :

-2x = 0

Therefore this set of equations has Infinite Solutions.

This can also be determined by graphing.

x = 23.78
