NEED HELP FAST!!!!!!!!!!!John the trainer has two solo workout plans that he offers his clients: Plan A and Plan B. Each client does either one or the other (not both). On Friday there were 3 clients who did Plan A and 5 who did Plan B. On Saturday there were 9 clients who did Plan A and 7 who did Plan B. John trained his Friday clients for a total of 6 hours and his Saturday clients for a total of 12hours. How long does each of the workout plans last?

Answer:45 minutes eachStep-by-step explanation:Set Plan A clients as x and Plan B clients as y to make a system of equations, the constant is the number of hours worked.3x+5y=69x+7y=12Now solve using substitution or elimination.  I will use elimination.-9x-15y=-18 I multiplied the whole first equation by -3 to eliminate x.9x+7y=12, add the equations-8y=-6 solve for yy= 3/4 of an hour or 45 minutesNext plug y into either equation3x+5(3/4)=6 Solve for x.3x+15/4=63x=2.25x=0.75, also 45 minutes To check plug in each variable value to each equation to see if they work if you need to.
