Answer:

For the first equation put in 4
For the second equation put in -12

(See below for writing)

Step-by-step explanation:

1. when you distribute 3 you multiply by three, so you have to do the opposite to find your answer.12/3=4

2. You just have to rewrite it. If you made the second one a positive equation, you would have 3x+ (-12).

For the writing part,

You could use the distributive property to simplify the equation and make it easier to solve for x.

Answer:

C. $x=20^{\circ}$

Step-by-step explanation:

Angle 6 and angle with measure 45° are vertical angles (opposite angles whan two lines intersect). By Vertical Angles Theorem, vertical angles are congruent, so

$m\angle 6=45^{\circ}$

Angle 6 and angle with measure $5x+35^{\circ}$ are the same side interior angles when two parallel lines are cut by transversal. The same side interior angles add up to 180°, then

$m\angle 6+5x+35^{\circ}=180^{\circ}\\ \\45^{\circ}+5x+35^{\circ}=180^{\circ}\\ \\5x=180^{\circ}-45^{\circ}-35^{\circ}\\ \\5x=100^{\circ}\\ \\x=20^{\circ}$
