Ex 2.2, 4 Sum of two numbers is 95. If one exceeds the other by 15, find the numbers.Let first number = π₯ Given, 2nd number exceeds the other by 15, Second Number = x + 15 Given, Sum of two number = 95 π₯+π₯+15=95 2π₯+15=95 2π₯=95β15 2π₯=80 π₯=80/2 π₯=ππ Thus, First number = x = 40 Second Number = x + 15 = 40 + 15 = 55
