If this is: 8x - y = 20 -5x = y - 8 8x - y = 20 -5x - y = -8 multiply by -1in order to eliminate y; 8x - y = 20 5x + y = 8 add both equations; 13x = 28 x = 28/13 substitute the value of x into the one of the equations in order to find y. For example, substitute it into the first one; 8(28/13) - y = 20 224/13 - y = 20 multiply both sides with 13; 224 - 13y = 260 224 - 224 - 13y = 260 - 224 -13y = 36 multiply both sides by -1; 13 y = -36 divide both sides by 13; y = -36/13 So the solution set is (28/13, -36/13) Check: 8(28/13) -(-36/13)= 224/13 + 36/13 = 260/13 = 20 -5(28/13) = -36/13 - 8 ? -140/13 = -36/13 -8 ? -140/13 = -36/13 - 8(13/13) ? -140/13 = -36/13 - 104/13 ? -140/13 = -140/13

http://wiki.answers.com/Q/27132028_what_comes_nextmes next? 2 7 13 20 28 ..... 2+(5)=7+(6)=13+(7)=20+(8)=28+(9)=37 therefore next number is 37
37. The difference between two consecutive numbers goes on increasing. 7-2=5; 13-7=6; 20-13=7; 28-20=8; 37-28=9...and so on.
37. In the sequence 2, 7, 13, 20, 28... each number in the pattern increases 1 more than that previous incrament, starting with 5 from 2 to 7.2 7 13 20 28 37 47 58 70 83 97...
37, 47, 58, 70, ... Each time the difference in the sequence increases by 1. From 2 to 7, we increase by 5 From 7 to 13, we increase by 6 From 13 to 20, we increase by 7 From 20 to 28, we increase by 8 From 28 to 37, we increase by 9, etc..
