we have

Solve for w means that clear variable w

Group terms that contain the variable w, and move the other terms to the opposite side of the equation

Factor the variable w

Divide both sides by 


therefore
<u>the answer is</u>

30 choices for first seat
29 for 2nd
28 for 3rd
27 for 4th
answer is 30*29*28*27=657720 ways

The answer is definitely 3
If we collect like terms of the first equation, we can simplify to
2x - 8 = 180
If we add 8 to both sides, we get
2x = 188
And that means x = 94
If we substitute this into the second equation, we get
7(94) - 8 = ?
7 x 94 is equal to 658
658 - 8 = 650
