3) Solve the equation:5+x=-7

5) 14x+6-4=13x-2

6) 4.1q - 5.1 - 5.4q = 2.3q - 5.4

7) -2(3b+3) + (7b-4) = 0

8) 8z = -16

9) 12t = -76

10) -10.8x = 21.6

11) z/19 = -9

20) Two minor league baseball players got a total of 254 hits. Washington had 8 more hits than Sanchez. Find the number of hits for each player?

X for sanchez and (x+8) for Washington

X+x+8=254

2x+8=254

21) In a recent yr. the total sales at restaurants A were 175000 more than restaurant B. total sales at the two stores were $575000000, what were the sales for the year at each store?

X = Rest B

X+175000 = Rest A

X+x+175000 = 575000000

22) A new cruise ship line has just launched 3 new ships. The PP, the CP and the MP. The CP has 16 more deluxe staterooms than the PP. the MP has 18 fewer deluxe staterooms than four times the number of deluxe staterooms on the PP. find the number of deluxe staterooms for each ships if the total deluxe staterooms for the three ships is 1012.

PP = X

CP = x+16

MP = 4x-18
