Answer:
Your answer is A 7,040 yards.
Step-by-step explanation:
----------------------------------------------------------------
Define x:
----------------------------------------------------------------
Let the number be x
----------------------------------------------------------------
Construct Equation :
----------------------------------------------------------------
x- 18 = 7x
----------------------------------------------------------------
Take away x from both sides :
----------------------------------------------------------------
-18 = 7x - x
----------------------------------------------------------------
Combine like terms :
----------------------------------------------------------------
-18 = 6x
----------------------------------------------------------------
Switch sides :
----------------------------------------------------------------
6x = -18
----------------------------------------------------------------
Divide by 6 on both sides :
----------------------------------------------------------------
x = -3
----------------------------------------------------------------
Answer; The number is -3.
----------------------------------------------------------------
(X,y)=(4, -1)
