x + 5 : 3x + 11 = 13 : 17
so
x + 5 / 3x + 11 = 13 / 17
by cross multiplication we get
( x + 5 ) × 17 = ( 3x + 11 ) × 13
17x + 85 = 39x + 143
39x - 17x = 143 - 85
22x = 53
x = 53 / 22
so
x + 5 / 3x + 11 = 13 / 17
by cross multiplication we get
( x + 5 ) × 17 = ( 3x + 11 ) × 13
17x + 85 = 39x + 143
39x - 17x = 143 - 85
22x = 53
x = 53 / 22
