Since the second equation gives a value for a, we can substitute it into the other equation to find a value for B.

Let's substitute b-2 into the first equation wherever there is an a.

a - 3b = 4
(b-2) - 3b = 4
b - 2 - 3b = 4
-2 - 2b = 4
-2b = 6
b = -3

Now let's find a by substituting -3 into either of the equations to find the value of a.

a = b - 2
a = -3 - 2
a = -5

So your solution set  is (-5, -3)

Mr.bonds math class starts at 11:30 if the class ends at 1:00 how long is his teaching.
Irina-Kira [14]
11:30 and 1:00
assuming that it is
11:30 AM to 1:00 PM and not 11:30 AM to 1:00 AM

11:30 to 1:00 cannot be directly counted
the hours go like  this
1,2,3,4,5,6,7,8,9,10,11,12=AM
then after 12AM then
1,2,3,4,5,6,7,8,9,10,11,2=PM

60 minutes in 1 hour so
11:30=11 hours and 30 mins
how far to 12 AM?
12 AM=12 hours=11 hours and 60 minutes
11 hours and 60 minutes-(11 hours and 30 mins)=30 minutes

then from 12 AM to 1 PM=1 hour so
time total difference is 1 hour and 30 minutes
