In isosceles pqr with base , pq = 2x + 3, and pr = 9x - 11. what is the value of x?

First, draw and label a rough sketch of an isosceles triangle. Now put in the values of pq=2x+3 and pr=9x-11

You know that the triangle is isosceles, therefore, the sides pq and pr are identical.

Now, make the equations equal to each other to find the value of x.

2x+3=9x-11
3+11=9x-2x
14=7x
14/7=x
2=x

Therefore the value of x=2.

Hope I helped :)

Hi!

So really focus on the fact that he started at $230, and then added an amount of money which we'll call x, which made his total equal $599.

Take the parts I put in bold, and write the equation.
$230 + x = $599

Now we need to find x.

Whatever we do to the equation, we do it to both sides.
Our goal is to isolate x on one side.

Subtract 230 from both sides.
$230 - $230 + x = $599 - $230
x = $369

The answer is A. $230 + x = $599 x = $369

Hope this helps! :)
