 * Try It!!!! **

//**1.**//  x - 4 = 10 **//2.//** //2x - 4 = 10// **3.** //5x - 6 = 3x - 8//
 * 4.** //2(3x - 7) + 4 (3 x + 2) = 6 (5 x + 9 ) + 3//

A little Words Added? **E** **quation**: x + y= 100 ** X **  =  the number of tickets **Totaled money collected** = 8.5x +4.5y=7300 =700 and y= 300 **Equation**: x + y=30,000 1.  x+y=30,000 2.       Total Investment= .05x + .08y=21,100
