stiv31 [10]2 years ago
5 0
My answer is probably 40+40 or 40×40or 40÷40 cause 40 times 40 equals might equal 1,600 or1,000 40 plus 40 equals 80 tho so that's my best guess 40 divided by 40 is probably just the same as 40 times 40 1,000 or 1,600.

SOLVE RIGHT NOW PLEASE. Determine the solution to the system of equations below by using the ELIMINATION METHOD.
KiRa [710]

Answer: x=4 and y=3

Step-by-step explanation:

We start eliminating the same numbers with the same variable. So we take out 5y on both equation. We then subract 3x to 6x and we do the same to the right side. We end up having 3x=12 and then we divide 12/3=4. We plug 4 on the x values in one of the equation to find out the y value on that equation. You end up with y=3 and then plug that in the same equation on both to see if its right. Finally after that its correct.
