Answer:
x= 4
y= 1
Step-by-step explanation:
Let's call this equation one
2x+3y=11
Let's call this equation 2
x-3y=1
Firstly I rearranged equation 2 and made x the subject of the formula to get :
x= 3y+1
Since I have x in terms of y, I then substitute equation 2 in equation one :
2x+3y=11
2(3y+1)+3y=11
6y+2+3y=11
9y=11-2
9y=9
y=1
from equation two, I can substitute y as one to solve for x
equation two---> x=3y+1
x= 3(1)+1
x=4
so y=1
and x=4
We know that these values are true because when we substitute them into the starting equations they r true
