Answer:

$x=-7$

Step-by-step explanation:

$-x+8+3x=-6$

$8+3x-x=-6$

$8+2x=-6$

$8+2x-8=-6-8$

$2x=-14$

$2x/2=-14/2$

$x=-7$

Answer:

x = -7

Step-by-step explanation:

Move over all the numbers and variables to one side and equal them to zero. The equation should now look like this: -x+8+3x+6=0

Combine like terms! Add -x+3x to get 2x and add 8+6 to get 14.

The equation should now read: 2x+14=0

Subtract 14 from both sides to show: 2x = -14

Get x by itself! Divide both sides by 2 to get x = -7

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

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