Applied problems of one variable linear equation in Grade 6 of Mathematics A two digit number whose number on the tenth digit is 5 times larger than that on the individual digit. The sum of the number on the tenth digit and the number on the individual digit is equal to 1 / 8 of the number to find the two digit number
Let ten digits be x, then one digit be X-5, then x + X-5 = 1 / 8 (10x + X-5) and x = 7, so this two digit number is 72
