If 5a=-4b+5 and 3a=-2b+3, what is 6b?
Misha Larkins [42]
There are two equations and two variables. You can solve for each variable using either the elimination method or the substitution method. Here, I believe the elimination method would be best:
5a = -4b + 5
3a = -2b + 3
You can multiply the second equation by two, so the 4b and -4b in both equations will cancel each other out when you add them. So:
5a = -4b +5
6a = 4b +6
Add both equations together.
11a = 11
a = 1
Plug in the a value into any of the previous equations:
5(1) = -4b + 5
-4b = 0
b = 0
So, since we know that b = 0, 6b is also 0.

 A road has a 16.7% grade.<br>Why might we want to warn drivers of a grade like this?
never [62]
The higher the percentage, the steeper the grade and the steeper the hill. This warning is issued so drivers are more careful (otherwise they would probably get into more accidents).
