Help me simplify and explain please

X=-34

Step-by-step explanation:

#1. multiply 3 to (x-2) and -4 to (x+7) you should get this: 3x-6-4x-28

#2. Then move the -4x and switch it with -6 so it should look like this: 3x-4x-6-28

#3. Do the calculation: -x-34

#4. move -34 to the answer side of your equation, should look like: -x=34

#5. move the negative from x to 34 your answer should look like: x=-34

#6. Celebrate! WooHoo! you just finished!!!
