What is the value of x?

enter your answer in the box.

x = ?

20

Step-by-step explanation:

These are vertical angles, which means that the measurements would be the same. Set the two angles equal to each other.

3x + 50 = 6x - 10

Isolate the variable, x. Subtract 6x and 50 from both sides.

3x (-6x) + 50 (-50) = 6x (-6x) - 10 (-50)

3x - 6x = -10 - 50

Simplify.

-3x = -60

Isolate the variable, x. Divide -3 from both sides

(-3x)/-3 = (-60)/-3

x = -60/-3

x = 20

20 is your answer for x.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
