S+D+K=155
K=S+10
D=S-20
--------------------------------
S+(S-20)+(S+10)=155
S+S-20+S+10=155
3S-10=155
3S=165
S=165/3=55
---------------------------------
If S=55,
K=55+10=65
D=55-20=35

Therefore, Sarah had worked for 55 hours, Kate had worked for 65 hours and Dave had worked for 35 hours.
The first step for creating our expression is to know that $10 is the amount that depends on how many hours he works. This means that $10 will have an x variable by it. Since we are trying to get a total of $305,, the expression will equal to it and $55 will be our constant. This looks like the following:
55 + 10x = 305
Now we can start to solve by moving the constant to the right side of the equation and then change its sign.
10x = 305 - 55
Subtract the numbers on the right side of the equals sign.
10x = 250
Finally,, divide both sides of the equation by 10 to get your final answer.
x = 25
This means that Tyler needs to work 25 hours in order to buy the video game system.

The slope is 1, so put either “x” or “1” and the y-intercept is at the origin so it’s 0, so put “(0,0)”
