Problema Solution
Gerald can complete a math assignment in 2 hours and a physics assignment in 1 hour. If he has 8 hours to complete a set of assignments, how many math assignments can he complete if he decides to leave the science assignments for the next day? This situation is given by 2x + y = 8, where x is the number of completed math assignments and y is the number of completed science assignments.
Answer provided by our tutors
he decides to leave the science assignments for the next day means y = 0
we need to find x from the equation 2x + 0 = 8
2x = 8
x = 8/2
x = 4 math assignments
He can complete 4 math assignments in 8 hours.
