The idea is to group up the terms into two groups, factor each group and then factor out the overall GCF

2x - 18 + xy - 9y
(2x - 18) + (xy - 9y)
2(x - 9) + (xy - 9y)
2(x - 9) + y(x - 9)
(2 + y)(x - 9)
(x - 9)(2 + y)

⇒ x = (-2)

2)

⇒x - (-4) = -6

⇒ x + 4 = -6

⇒ x = -6-4

⇒ x = -10

3)

⇒2(x-1) = -200

⇒ x - 1 = -200/2

A wood frame costs $1.50. Use a property to write an equivalent expression for the cost of a wood frame.
podryga [215]
Let the width of the frame = x
Let the cost of a linear foot of the frame = y
Let the inside dimension of the length of the frame = a
Let the inside dimension of the width of the frame = b.

The total length of the frame = 2*a + 4x
The total width of the frame = 2b

The total amount of the frame in feet is (2a + 4x + 2b)*y = Cost
