Answer:
x = 
Step-by-step explanation:
Given
3x + 2 = 6 ( subtract 2 from both sides )
3x = 4 ( divide both sides by 3 )
x = 
Easy question.
So, the slope is -x and the y-intercept is at -4.
y = -x - 4
Use this equation and you will find:
y = -2 - 4
y = -6
Answer: (2, -6)

Example to help you out!
May rides her bike the same distance that leah walks. may rides her bike 10 km/h faster than leah walks. if it takes may 1 h and leah 3 h to travel that distance, how fast does each travel?
----------------------------------------
May DATA:
time = 1 hr. ; rate = x+10 mph ; distance = rt = (x+10)*1 mi
--------------------
Leah DATA:
time = 3 hr. ; rate = x mph ; distance = rt = 3x mi
-----------------------
Equation:
distance = distance
x+10 = 3x
2x = 10
x = 5 mph (Leah's rate)
x+10 = 15 mph (May's rate)
Step-by-step explanation:
Suppose the three sides are a, b, and c, with c being the longest, a being the shortest
first equation: c=(a+b)-66
second equation: 2a=c-55=> c=2a+55
plug c=2a+55 into the first equation: 2a+55= a+b-66 => b=a+121
a+b+c=a+(a+121)+(2a+55)=7272 =>4a+176=7272 =>a=1774
a=1774, b=1895, c=3603
