there are 130 mango and orange trees in a farm the number of mango trees is20 more than the number of orange trees how many mango trees are there
, 75 mango trees, let orange trees be x and let be mango trees be x + 20, the equation is:, x + x + 20 = 130, 2x + 20 - 20 = 130 - 20, 2x = 110, x = 55, there are 55 orange trees. so, 130 - 55 equals to number of mango trees which equals to 75.,
