Solve the following system of equations.

Question

x + 4y = 3
3x + 12y = 5

Answer 1

Here we go, Brittany!

 

x + 4y = 3

3x + 12y = 5

 

Let's solve the first for x.

 

x = 3 - 4y

 

Now, substitute.

 

3(3 - 4y) + 12y = 5

9 - 12y + 12y = 5

0 = -4

 

Hey, that's not true! Therefore, there is no solution!
