To solve for y, you want to have all unknowns on one side and knowns on the other. to do this, we can divide both sides by 0.6 so that the knows are on the second side and y on the other. then, we can simplify to solve for y
Answer:
Goodmorning! The answer in Explanation.
Step-by-step explanation:
Your answer would be A!!!
• if you multiply 5280*6=31680
• then 5280divided by 2
• being 2640
• then 31680+2640=34320 ft. which is your answer, A.

Answer:
(-3,2)
Step-by-step explanation:
1) -2x+y=8
you need to leave the Y alone on one side. Then, the term -2x goes to the other side with its opposite sign which is +.
y=8+2x
2) y=2x/(5-8)
3) 8+2x=2x/(5-8)
now, you need the x value. for that, you need to leave x alone on one side.
8+2x=2x/(-3)
8+2x=-(2/3)x
8=-(2/3)x-2x
8=-(8/3)x
8/-(8/3)=x
-3=x
4) you now have the x value. you need the y value. for that, replace the x in one of the given equations. let´s use the 1st equation.
-2x+y=8
y=8+2x
y=8+2*(-3)
y=2
result:
x= -3
y=2
