Asurvey showed that 70 customers bought white bread, 63 bought wheat bread, and 35 bought rye bread. of those who bought exactly two types of bread, 12 bought wheat and white, 5 bought white and rye, and 7 bought wheat and rye. two customers bought all three. how many customers bought only wheat bread?

The answer is 63, it says "63 bought wheat bread" and the question is who bought "only" wheat bread.

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
