Answer:
Step-by-step explanation:
Applying BODMAS here;
We first solve what is in the brackets:
9x - 81 -3 = -8x - 16
We then put the like terms together:
9x + 8x = -16 + 81 + 3
We then do the addition:
17x = -16 + 84
We then do the subtraction:
17x = 68
Simplifying this gives:
x = 
= 4
Answer:
x= -4
Step-by-step explanation:
A line is 180 degrees. This means that we can use the equation
60+x+124=180
Simplify:
184+x=180
x= -4
We can check this answer by plugging it back in:
60 + (-4) +124 =180
180=180
I hope this helps!

Answer:
-5
Step-by-step explanation:
y=mx+b --> M is the slope
therefor..
y=-5x-9
so a slope // to the first line with have equall slopes
Both lines have a slope of -5
