-30x-12y+36x-12y
Combine the x' s first
6x-12y-12y
Combine the y's
6x-24y is your answer
Answer with explanation:
<u>Part A: </u>
One solution.
The number of points of intersection represents the number of solutions. Since the two lines only intersect at one point, there is only one solution.
<u>Part B:</u>
(3, 4)
The point(s) of intersection marks the solution(s) to the lines. Since lines A and B intersect at the point (3, 4), the solution to the equation of their lines is (3, 4), or
, as coordinates are written as (x, y).
Answer:
Step-by-step explanation:
5x-4=20
5x=24: x=24/5
y=3x-12
y=3(24/5)-12
y = (72-60)/5
y=12/5
Answer:
-3x + 9
Explanation:
Because these two integers that is - and - is said to be added and write the sign of of greater or bigger number.
