This equation that you are asking of is a complex equation that inverse operations are needed in to solve it. First, use the inverse operation and add 8x to 6x. The 8x on the right side of the equation will cancel out. The 6x and the 8x will equal to 14x: 8x+6x+9=-19-8x+8x which now equals 14x+9= -19
Secondly, eliminate the constant terms by subtracting 9 on both sides of the equation: 14x+9-9= -19-9
Now the problem is 14x= -28
Third step - isolate the variable and divide 14 by -28. X should now equal -2.
14x/14= -28/14 which should equal x= -2
You can check and see that this is accurate by multiplying -2 to each coefficient that had x as their variable: 6(-2)+9=-19-8(-2)
-12+9= -19+16 which equals -3=-3
