Find the point of intersection:<br> 3x=y-2<br> 6x=4-2y
IgorC [24]
Answer: (0, 2)

3x = y - 2
6x = 4 - 2y

3x = y - 2
- y - y
-y + 3x = - 2
- 3x - 3x
-y = - 3x - 2
/-1 /-1
y = 3x + 2


6x = 4 - 2y
+ 2y + 2y
2y + 6x = 4
- 6x - 6x
2y = - 6x + 4
/2 /2
y = -3x + 2


y = 3x + 2
y = -3x + 2


3x + 2 = -3x + 2
- 2 - 2
3x = -3x
/3 /3
x = 0


y = 3x + 2
y = 3(0) + 2
y = 2

(x, y) --> (0, 2)

Therefore, the two equations intersect at (0, 2)



Hope this helps!

Can somebody explain please?
Scilla [17]

Answer:

34 degrees

Step-by-step explanation:

considering the two lines are parallel:

(3x + 7) + (2x + 3) = 180 degrees

3x + 2x + 7 + 3 = 180 degrees

5x + 10 = 180

5x = 180 - 10

5x = 170

x = 170/5 = 34

the value of x = 34 degrees
