First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number, then this is a percentage decrease. ( copy and paste from skillsyouneed.com )

Answer:
x = 4
Step-by-step explanation:
-3x + 2 = -10x + 30
Add 10x to both sides and you get
7x + 2 = 30
Subtract 2 from both sides and you get
7x = 28
Divide both sides by 7 to get x by itself and you get
x = 4
Reminder whatever you do to one side you have to do to the other side!
