X=-2
Y=3
I guessed and checked, works for me most of the time
From second equation y = 8 - x so
7x + 2(8 - x) = -14
5x = -14 - 16 = -30
x = -6
and y = 8 - -6 = 14
Answer x=-6,y=14
Answer:
4 gallons
Step-by-step explanation:
as martizas used up 3/4 gallons, we can calculate the fraction of gas left using: 1−3/4=1/4.
so now we use the fraction we calculated to times with the total volume of gas : 1/4×16=4 gallons
I’m pretty sure the answer is D
