Answer:
x=1/2
Explanation:
3x+y=3..............(1)
7x-y=2...........(2)
for equation (1)
y=3-3x...........(3)
substitute y=3-3x into equation(2)
7x-(3-3x)=2
7x-3+3x=2
C L T
7x+3x=2+3
10x=5
x=5/10
We can solve this system of equations using elimination.
In this case, we can eliminate y by adding the two equations:
Divide both sides by 10
