Answer:

{x,y} = {-1,3}

Step-by-step explanation:

Answer:

Yay! System of equations!

Step-by-step explanation:

So, to solve this with substitution!

The best one to start with is the bottom one, x+4y=11

So, we can move 4y to the other side of the equation to get the value for x!

[tex]x=-4y+11[/tex]

So, to substitute this, we just input this x-value into the other equation!

[tex]3(-4y+11)+5y=12[/tex]

So, we have our equation, so let's solve!

[tex]-12y+33+5y=12\\-7y=-21\\y=3[/tex]

So, there is our y-value! Now to input this value into either one of the equations to find the x-value!

[tex]x+4(3)=11\\x=-1[/tex]

So, there is our solution!

Hope this helps!
