You can actually do it either way, you could distribute first and then combine, you would get the same answer. I guess it just depends on what you find easier. Here is how to solve it both ways:

Combining First:

8(5x+9x+6)=160

8(14x+6)=160

112x+48=160

112x=112

x=1

NOT Combining First:

8(5x+9x+6)=160

40x+72x+48=160

112x+48=160

112x=112

x=1

so, you would get the same answer both ways, it is of personal preference what you do first.

A rectangular poster has an area of 190 inches squared. The height of the poster is one inch less than twice its width. Find the
Annette [7]
Set the height to h, and the width to w.

We know that wh=190 and h=2w-1.

Substituting 2w-1 for h, we have:

w(2w-1)=190

So:
2w^2-w-190=0

Factoring this equation, we get (2w+19)(w-10)=0.  The solutions to this equation are -9.5 and 10, but clearly the width must be positive, Substituting 10 for the width, we get 10*2-1=19 for the height.
