Answer:

x=\frac{1}{5}

y = -\frac{1}{15}

Step-by-step explanation:

4x - 3y = 1

x + 3y = 0

Req To Solve With Elimination:

Make Them Equal:

-> 4x - 3y = 1

-> 4x + 4 . 3y = 0

Simplify:

->  4x - 3y = 1

-> 4x + 12y = 0

-> 4x - 4x - 3y - 12y = 1

-> -3y - 12y = 1

-> -15y = 1

-> y = -\frac{1}{15}

-> x+3(-\frac{1}{15} )=0

-> x -\frac{1}{5}=0\\

-> x=\frac{1}{5}

Answer:

4x – 3y = 1

x + 3y =​

Adding the equations gives us:

5x =1

x = .2

since 4x - 3y = 1

then -3y -1 = -4x then we multiply by -1

3y +1 = 4x

3y = 4*.2 -1

3y = .8 -1

3y = -.2

y = -.2 / 3  = -0.066666666...
