Question

What is the value of x?

Enter your answer in the box.

x =

Two intersection lines. Angle formed at the top is labeled 3 x plus 50 degrees. Angle formed at the bottom is labeled 6 x minus 10 degrees.

Answer 1

x would you equal 20.

Answer 2

20

Explanation:

So, both of those angles are equal to each other because they are congruent. So, we can set their equations equal to each other to find x.

Solve it like this:

3x + 50 = 6x - 10

-3x -3x (always subtracts the variables first (x), then the other numbers)

50 = 3x -10

+10 +10

60 = 3x

Then, divide both sides by the number next to the variable (3)

60/3 = 20, 3x/3 = x

So, you get:

20 = x
