Make one of the variables drop out.
I'd go for the y since it's easiest in this problem.
Time the top equation by -1.
This changes the system to:
Add the equations.
The equation would be:
Or simply:
Solve for x by dividing.
Then, plug x into one of the original equations to find y.
I'm going to use the first one since the numbers are smaller, but you CAN use either.
Put these into an ordered pair.
(0,1)
That is your answer.
Hope this helped!

Answer:
3.14×48^2= 7234.6
Step-by-step explanation:
to find the area of a circle the formula is A=3.14r^2.
U got to divide 78 and 12 then
Answer:
x = -17/26
Step-by-step explanation:
4(7x - 1) = 3(2x + 1) - 4(x + 6)
distribute 4 through the parentheses (do 3 and -4 as well)
28x-4=6x+3-4x-24
collect like terms
28x-4=2x+3-24 --> 28x-4=2x-21
move the variable
28x-2x-4=-21
collect like terms
26x=-21+4 --> 26x=-17
then divide
hope this helps and makes sense! :)
