Answer:
X=3,y=-4
Step-by-step explanation:
The only change is x so you could figure it out that way or do this:
4x=12 by subtracting the secound equation by the first one (since both y's are being multiplied by the same thing you can do this to cancel them out while making one equation). and than figure out x=3 from there you input that into eithger equation to figure out y. Hope this helped!
Answer:
x=-1
Step-by-step explanation:
3x+12-8x=19+2x (combine liked terms)
-5x+12+19=2x (move variable to the left-hand side and change its sign)
-5x-2x+12=19 (combine liked terms)
-7x=19-12 (divide both sides of the equation by -7)
x=-1
I think it is the graph should be redrawn with the vertical axis beginning with $0.
You would run 5mi and your friend would run 4mi. 5*8=40 and 4*10=40 40 the lowest shared factor.
