Equations and Measures
Starter
Solve these equations:

(a) 3x = 12
(b) 3x + 4 = 16
(c) 4x + 4 = 16
(d) 2x + 4 = 16
(e) -2x + 4 = 16
(f) - x + 4 = 16
Example
The perimeter of this rectangle is 16 cm. Find the dimensions of the rectangle.
L.O. - Form equations from different measures, and then solve the equations.

Solve these equations:

(a) 3x = 12
x = 4
(b) 3x + 4 = 16
x = 4
(c) 4x + 4 = 16
x = 3
(d) 2x + 4 = 16
x = 6
(e) -2x + 4 = 16
x = -6
(f) - x + 4 = 16
x = - 24

x + 2
x + x + 2 + x + x + 2 = 16
4x + 4 = 16
4x = 12
x = 3
x + 2 = 5
