What is systems of linear equations

In mathematics, a system of linear equations is a collection of one or more linear equations involving the same set of variables. For example, is a system of three equations in the three variables x, y, z.

Example:

x + z = 6.

z − 3y = 7.

2x + y + 3z = 15.

$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
