Question

Which is the Value of x?

X=14

X=28

X=67

X=37

Answer 1

=28

Explanation:

(3-21)= 63

3= 63+21

3= 84

= 84:3= 28

Answer 2

x = 28

Explanation:

3x - 21 = 63, I am making them equal to each other because of the vertical angle theorem.

3x - 21 = 63, add 21 to both sides

3x = 84, divide 3 to both sides to make x by itself

x = 28
