X+5y=-11 (1)
2x-3y=17 (2)
2(1)-(2)
2x+10y-2x+3y=-22-17
13y=-39
y=-3
Sub y=-3 in (1)
x+5(-3)=-11
x=4
So x+y= -3+4 =1
Answer:
you have to find the smallest common denominator
Step-by-step explanation:
so once the fractions have the same denominator you can add them easily and simplify
Sally = 1/3
Jerry = 5/6
David = 1/2
Mona = 1 - 7/8 = 1/8
So, the biggest fraction among them is 5/6.
Jerry has completed the most work time.
