I don’t really know what the answer is but I’ll try so - 6/7 = 6/7 3 15/44 = - 3 15/44 -2 5/22
Answer:
Check my explanation
Step-by-step explanation:
1. x=-7y
2(-7y)-8y=22
-14y-8y=22
-22y=22
y=-1;x=7, I used subtitution because that process was easier.
2. x=3+y
7(3+y)-y=-3
21+7y-y=-3
21+6y=-3
6y=-24
y=-4; x=-1, I used subtitution because that process was easier.
3. x=1 and y=1, I used elimination because that process was easier.
4. x-3=4x-9
-3x=-6
x=3; y=0, I used subsitution because that process was easier.
C the third one
Just plug in each answer givin into both equations untill both fit in.
$24/5 = $4.8 x 3 = $14.4
$24/6 = $4 x 1 = $4
$14.4 + $4 = $18.4
$24 - $18.4 = $5.6
Answer:
-4.5
Step-by-step explanation:
I added 3.25 and .5=3.75. Then i did 0.25*-6=1.5. -1.5+3.75=2.25. 2.25*2=-4.5
