What is the solution to the system of linear equations? 2x+4y=20 and 3x+2y=26​
Vaselesa [24]

Answer:x=8,y=1

Step-by-step explanation:

2x+4y=20

So, 4y=20-2x

So,2y=10-x

Now we can use this information to use in the second equation

3x+2y=26

3x+(10-x)=26

2x+10=26

2x=16

x=8

Now that we know that x=8, then we can solve for y.

2x+4y=20

2(8) +4y=20

16+4y=20

4y=4

y=1
