Fine the point of intersection using the substitution method. 4x - 7y = 20 And x- 3y = 10 please help me

i got 10.28 but that rounds up to 10.3

$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
