we can equate vertex with vertex then;
a=p
b=q
c=r
for starters

since b=q, and they give you eqaustions for b and q; then write the equations equal to each other and it should be a simple matter to solve for v

yeah but Im not sure how to do that

what is the equation for q?
since b = q then its also true that:
(equation for b) = (equation for q)

good, and can you finish the setup? ill help you thru it once i see that you can at least set it up

8v9 is Q

so 8v9=5v+6??

good, then
(equation for b) = (equation for q)
5v+6 = 8v9

so then do you subtract 5 from both sides?

close, there is a v stuck to the 5, so lets subtract 5v from each side for starters

5v+6 = 8v9
5v 5v

6 = 3v  9
what do you think another good move would be?

add 9 to both sides?

correct
6 = 3v  9
+9 +9

15 = 3v
only one more move left, what do you think we should do?

divide 3 on both sides to get v

excellent
15/3 = 3v/3
5 = v
so now that we know a normal looking value for v, we can use it to find the values of b and q right?

Like plug 5 into the original problem?

yes, and it should work in either equation for b or for q and give us the same value

5(5)9?

it looks like you might have blended the 2 equations into an abomination of desolation :)
b = 5v+6
= 5(5)+6
q = 8v9
=8(5)9

so 16
and 31?
I feel like thats totally off

b = 5v+6
= 5(5)+6
= 25 + 6
= 31
q = 8v9
=8(5)9
= 40  9
= 31
b = q = 31
