-7x - y = 0

7x + 8y = -6

What is the result of subtracting the second equation from the first?

-14x - 9y = 6

Step-by-step explanation:

subtract the similar terms from each other

-7x - 7x = -14x

-y - 8y = -9y

0 - - 6 = 0 + 6 = 6

put it together:

-14x - 9y = 6

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
