Answer:
30
Step-by-step explanation:
You can find that out by first putting two equations in slope-intercept form y=mx+b by solving for y.
3y - x = 2
3y = x+2
y = (1/3)x + 2/3
9y = 3x + 6
y = (3/9)x + 6/9
y = (1/3)x + 2/3
They are the same line as you can see in the final step.
Since the two lines are the same line, (they "coincide") they are coincident.
Coincident means there are an infinite number of solutions, and since they are the same line, there are an infinite number of solutions.
Answer:
r = -3
Step-by-step explanation:
Add the like terms: 8r = -24
Isolate r by dividing each side by 8: r = -24/8
Simplify: r = -3
Hope this helps
Let's take a peek of each term, to be specific, the exponent of the variables only, to see what degree each term is

so...which term has the highest degree? well, that one, is the degree of the polynomial
