Eliminating by multiplying <br> X+3y=1<br> -5x+4y=-24
gavmur [86]

Answer:

y = -1         x = 4

Step-by-step explanation:

(X+3y=1) 5            Multiply this equation by 5 to cancel out the x

-5x+4y=-24

-5x + 4y= -24

+ 5x + 15y = 5       Add both equations together

19y = -19                Divide both sides by 19

y = -1

Plug -1 for y into one of the equations

x + 3(-1) = 1             Multiply 3(-1)

x - 3 = 1

 + 3 + 3                  Add 3 to both sides

x = 4
