2(x + 3)= 5? x + 3 = 2½ x = -½
(x+5)/4
In an addition sum, if the missing number is the first number, for example, x + 5 = 10, then to find x, perform the sum 10 - 5, producing the solution x = 5. In a subtraction sum, if the missing number is the second number, for example, 7 - y = 4, then to find y, perform the sum 7 - 4 = 3, production the solution y = 3.
Let the number be x and so if 3x+5 = 41 then x = 12
