So one easy way is to make the equation equal to only one place holder so
-7x-4y=16
add 7x to both sdies
-4y=16+7x
multiply both sides by -1
4y=-16-7x
divide both sides by 4
y=-4-7/4x
subsitute values for x and get values for y
exg
if x=0 then y=-4
if x=1 then y=-5 3/7
etc
Answer:

Step-by-step explanation:
minutes to hours:
525600/60
8760
hours to days:
8760/24

Let's use the formula to find the perimeter of a rectangle.
2l+2w=120
We know that the length is twice its width; the equation would be:L=2w
We can plug that in to the formula.
2(2w)+2w=120
4w+2w=120
6w=120
120÷6=20=w
Since the length is twice its width, 20×2=40. The length is 40 cm.
The width is 20 cm.
