x = 45 x 100/19 = 236.84
x + 30 = 64 Therefore, x = 64 - 30 x = 34
x=-6
x + 2y = 27 2x - y = 19 y = 2x - 19 x + 2(2x - 19) = 27 x + 4x - 38 = 27 5x = 65 x = 13 y = 2(13) - 19 y = 7

19/30 = x/100 x= 19*100 / 30 x= 1900 / 30 x= 63.333333....
49 - 30 equals = 19
x equals 6 5 times 6 equals 30
810000
X percent of 30 equals 24 X% * 30 = 24 X% = 24/30 X% = .8 X = 80%

19 x 1 = 19
x + 10 = 19 x = 19 - 10 x = 9
19 plus 54 equals 73. when you subtract like this x+19=73 X+19=73 -19 -73 0 54
x = 45 x 100/19 = 236.84
