Answer:

x = -7

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
