Reorganize the equations;
y -2x = -3.5
-2y+x = -14
Multiplying equation II by 2
y-2x = -3.5
-4y+2x= -28
----------------
-3y=24.5
y=

y= -8.17
Replacing value of y in equation 2;
-2(-8.17)-2x=-3.5
16.34-2x=-3.5
16.34+3.5=2x
19.84=2x
x=9.92
You divide your fraction I hope this helps
Starting time=1:45
ending time =3:30
add to get=4:75
one hour=60 minutes
75-60=15
answer=5:15
(x-3)(6x-2)
x*6x + x*(-2) -3*6x (-2)*(-3)
6x^{2} -2x-18x+6
6x^2-20x+6
You change the fraction so that they will have the same denominator. This makes it 5 6/8 minus 3/8. The answer is 5 3/8
