7 0

Answer: <em>x</em>=35

Explanation:

Use the theorem that an exterior angle of a triangle equals the two remote angles. Therefore, 147=(x+42)+(2x). Now solve for <em>x</em>

147=3x+42

3x=105

<em>x=35</em>

What is the intersection of lines for the two equations y+3x=1 and y-6=2x?
netineya [11]

Answer:

Step-by-step explanation:

Let's reformat both equations so that y is by itself on each side:

y = -3x + 1

y = 2x + 6

Since we y isolated to one side in both equations, we know the right-hand sides must be equal:

-3x + 1 = 2x + 6

Solving for x will give us the x-coordinate of the point of intersection:

-5x = 5

x = -1

Plugging in this x-coordinate to either of the above equations will give us the y-coordinate of the point of intersection:

y = -3(-1) + 1

y = 4

Therefore, the point of intersection is (-1, 4)
