-2x+3 - (5 - 6x)
pretend that there is a -1 in front of the bracket
mutiply the bracket by -1
(-1)(5)=-5
(-1)(-6x)= 6x
-2x+3-5+6x
-2x+6x+3-5 ( combine like terms)
Answer: 4x-2
Answer:
10%
Step-by-step explanation:
Let the third number is X.
then first number = (100-30)% of X
= 70% of X = 7X/10
Second number is (63X/100)
Difference = 7X/10 - 63X/100 = 7X/10
So required percentage is, difference is what percent of first number
=> (7X/100 * 10/7X * 100 )% = 10%
