Question

Solve by substitution:

4x-12y =5
-x + 3y = -1

Answer 1

4x-12y=5
4x+-12y+12y=5
4x/4=5/4
x=5/4 =1 1/4

4x+-12y=5
-4x+-12y=5
-12y/-12=5/-12
y=-5/12

-x+3y=-1
-x+3y-3y=-1
-x/-1=-1/-1
x=1


-x+3y=-1
-x+x+3y--1
3y/3=-1/3
y= -1/3

Answer 2

Carol! Thank you so much! I am to solve by substitution. I am a bit confused as to now having two separate y and x components, rather than one set of x and y/ If you have time, Please help me to understand/ Thank you. Carl
