1. ## Help with Isolating in Equations

Hello,

I'm having a little problem with my math problems. I'm 16 and from Iceland and I hope you forgive my bad English.

These are the equations I'm having trouble with:

a) p = 5 + at - I'm suppose to isolate the t.

b) y = 9(x - 7) - I'm suppose to isolate the x.

I get these outcomes (the signs look funny, I hope you get what I'm talking about):

a) t = 5/ap

b) x = y + 63/9

If I'm wrong, can you help me out?

My dearest thanks,

Gronfeldt

2. yeah i believe thats correct and just reduce the 63/9 = 7

Thanks for the help

$p = 5 + at$

$p - 5 = at$

$\frac{p - 5}{a} = t$

$y = 9(x - 7)$

$\frac{y}{9} = x - 7$

$\frac{y}{9} +7= x$

How are they correct?

I believe you correct I'll use this.
