Let n be the number unknown


2(n)-2=n+64


Use distribute property to remove parenthesis

2n-2=n+64


Move all n term to left side


2n-n-2=64


Combine like terms with n


N-2=64


Now add integer to right side by doing opposite sign


N = 64+2


Solve for n


N=66


Your number is 66


To check you substitute


2(66)-2=66+64

130. =130

(Geometry) PART A Find the value of X.
guapka [62]

Answer:

Part A: The answer is B.

As vertically opposite angles are equal

x+10=4x-35

10=3x-35

45=3x

x=15

Part B: The answer is D.

We'll substitute in the value of X in one equation.

x+10

=15+10

=25

As the two angles are equal bot must be 25 degrees.
