imatfaal Posted June 18, 2013 Posted June 18, 2013 matthewmath this smells like homework - so no one is just gonna give you an answer. try and make an equation that says the same as your prose
StringJunky Posted June 18, 2013 Posted June 18, 2013 ...he sum of three times a number and 11 is 32. Try reading it in reverse: 32 is...
gabrelov Posted July 28, 2013 Posted July 28, 2013 It says 3 times a number, we denote the number as variable x, so we multiply 3 to x and get 3x. The next set words says "and 11", note and means addition or add and the first words says "the sum". Is equal to 32 so we equate it to 32. here it goes 3x + 11 = 32, thus 3x + 11 - 11 = 32 - 11 3x = 21, dividing both sides by 3 you get 7 Substitute it to original equation to check your answer: 3(7) + 11 = 32 ----> 21 + 11 =32 -----> 32 = 32, correct
