Find the solution of this system of equations.
separate the x- and y-values with a comma.
x - 2y = -6
x - y = 12

x = 30, y = 18

Step-by-step explanation:

Given the 2 equations

x - 2y = - 6 → (1)

x - y = 12 → (2)

Subtracting (2) from (1) term by term will eliminate the term in x

||(x - x) + (- 2y - (- y)) = (- 6 - 12), that is

- y = - 18 ( multiply both sides by - 1 )

y = 18

Substitute y = 18 into either of the 2 equations for value of x

Substituting in (2)

x - 18 = 12 ( add 18 to both sides )

x = 30

the answer is a

step-by-step explanation:

39.00 x 24 = total installment price

carrying installment price - cash price

needed to save the .00/

$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
