Answer: (3,2)
Step-by-step explanation:
For this set of system of equations, let's use elimination method to find x and y. Let's eliminate y first. In order to do so, the y values have to be the same. Therefore, you multiply the top equation by 3 and the bottom equation by 4.
9x+12y=51
-16x-12y=-72
Now, we can add the 2 equations together for the y to cancel out.
-7x=-21
x=3
Since we know x, we can plug it into any of the equations to find y.
3(3)+4y=17
9+4y=17
4y=8
y=2
With out x and y value, we can put them into an ordered pair. (3,2)
2/7 - 5/21 = 6/21 - 5/21 (find common denominator first, then subtract)
6/21 - 5/21 = 1/21
3/4 = 63/84
5/7 = 60/84
7/12 = 49/84
63/84 + 60/84+ 49/84 = 172/84
172/84 - 4/84 = 168/84
The answer is 168/84, or 2. Hope this helped!
