a). X + X = 20
X = _________ |
b). X + 2X = 36 ____________ X = _________ |
c). 3X + X = 16 _____________ X = _________ |
d). 4X - X - 5 = 10 _____________ X = _________ |

First write down the equation, then simplify it, then solve it.

(I will write the first equation for you)

a). The perimeter is 18 feet. | How many X's are there around the
wholerectangle? | Equation: 2x + x + 2x + x = 18 Simplify it:_______________________ X =_____________ |

b). The perimeter is 40 inches. | Be careful!Not all the sides are labelled! | Equation:_______________________ Simplify it:_______________________ X =_____________ |

c). Find angle X: | What do all the angles of a triangle add up to? | Equation:_______________________ Simplify it: ______________________ X =_____________ |
