Step 1 :     7x - 3x - 4 = -1 +21
Step 2 :     7x - 3x - 4 = 20
Step 3 :     4x - 4 = 20
Step 4       4x -4 +4 = 20 + 4
                 4x = 24

Write an equation: The sides of a rectangle are x and ( x - 4 ). The perimeter is 87
Svetlanka [38]

The perimeter of a rectangle, is all of the sides added up.

In a rectangle, there are two widths (right and left), and two lengths (up and down)

So:

Perimeter = 2 × width + 2 × length.

To get the equation we just substitute in the values that we are given:

length = (x)

width = (x - 4)

perimeter = 87

So just put these values into:  perimeter = 2 × width + 2 × length:

87  =  2(x) + 2(x - 4)

_____________________________

Answer:

The equation is:       87 = 2(x) + 2(x - 4)

<em>(note: this can be simplified down like so:</em>

<em>87 = 2x + 2x - 8</em>

<em>87 = 4x - 8</em>

<em>95 = 4x</em>

23.75 = x
