Ok, so for example, we have an equation of 4x+5 = 17. To solve for x, we first subtract 5 on both sides. This is called Subtraction Property of Equality.

Y - x - 3 = 0
y = x + 3

y = x^2 - x - 12
x + 3 = x^2 - x - 12
x^2 - x - 12 - x - 3 = 0
x^2 - 2x - 15 = 0
(x - 5)(x + 3) = 0

x - 5 = 0 y = x + 3
x = 5 y = 5 + 3
y = 8

x + 3 = 0 y = x + 3
x = -3 y = -3 + 3
y = 0

so ur solutions are : (5,8) and (-3,0)

Perimeter of a rectangle is

2*width + 2*length

then multiply the perimeter by the cost per foot

2*(150ft) + 2*(200ft)

300ft + 400ft

700ft

700ft * $10/ft

$7000
