Option c
Answer:
y=-3x+20
Step-by-step explanation:
3/4x+1/4y=5
-3/4x -3/4x
1/4y=5-3/4x
divide the whole entire equation by 1/4 like this: (4)1/4y=4(5-3/4x)
Your answer is y=-3x+20
1.3 would be your answer because half of 2.6 is 1.3
let's say it holds "x" gallons of gas.
how much is 1/3 of that? well is just (1/3)x.
how about 1/2 of that? well is just (1/2)x.
we know that

The solution to the system is (-2,-8)
