Answer:
Multiply the first equation by 4.
Step-by-step explanation:
4(x+y=3) which gives
4x+4y=12
and
4x-y=7
Then subtract the two equations and the x variable will be eliminated.

Answer:
The answer is 10
Step-by-step explanation:
Trust me
20/2-10/5. You divide 20 by 2 and subtract that from 10 divided by 5
Answer:
Step-by-step explanation:
Because the y intercept is two our y=mx+b equation looks like this
y=mx+2
We then need to find a slope that gives us an x intercept of 3 or satisfies the coordinates of (3,0)
We can plug this in and solve
0=3m+2
-2=3m
-2/3=m
which means our final equation is
-2/3x+2
C
