Question

What is the Value of x?

Answer 1

the angles are on opposite sides of the vertex, so are called vertically opposite angles and are equal in their measures

so you can equate the 2 angles

8x + 16 = 3x + 84

now just solve for x

Answer 2

but how?

Answer 3

start by subtracting 3x from both sides of the equation

8x -3x + 16 = 3x -3x + 84

so

5x +16 = 84

now you should be able to solve the 2 step equation

Answer 4

okay so.. 5x + 16 and then + 84?

Answer 5

well you could but it just makes the solution harder to find.... try subtracting 16 from both sides of the equation.

Answer 6

okay.. 84-16=68 and then 5x-16?

Answer 7

5x + 16 -16 = 84 -16

what does the equation become..?

Answer 8

5x=68?

Answer 9

and then it would eequal 13.6?

Answer 10

it would be the value of x

Answer 11

13.6 would be the value of x right?

Answer 12

correct
