Answer:
2x + (-2x + 3) = 3
2x - 2x +3
0 + 3
3
2x-7 + (-2x) = -7
2x -2x - 7
0 -7
-7
-(5x -1) + 5x = 1
-5x +1 + 5x
-5x + 5x + 1
0 + 1
1
Step-by-step explanation: In addition, the parentheses help identify the individual addends. If adding a negative number, it is the same as subtracting. If there is a negative sign outside the parentheses, as in example c, you must distribute it: the signs of the numbers within the parentheses must be reversed when the parentheses are removed.

Step-by-step explanation:
14 + 8m = 14 - 3m - 5m
Combine like terms
14 + 8m = 14 - 8m
Add 8m to each side
14 +8m +8m = 14 -8m +8m
14 +16m = 14
Subtract 14 from each side
14-14 +16m = 14-14
16m = 0
Divide by 16
16m/16 = 0/16
m = 0
You convert a decimal to a fraction by putting the digits to the right of the decimal point over "1" followed by the same number of zeros. (Most folks learn this in 3rd or 4th grade.)
0.66 = 66/100 . . . . . 2 decimals, so the denominator is 100
Then you reduce the fraction by canceling common factors. It helps to know your times tables and divisibility rules. (Or you can have your calculator do it.)
0.66 = 66/100 = 33/50
1.00 = 100/100 = 1
Answer:
Step-by-step explanation:
First, turn the word problem into an equation:
n(a number) was divided by 2

followed by this quotient beying multiplied by 4
*4
the product was added to 9
*4+9
the total sum was 25
*4+9 = 25
use PEMDAS to solve the equation
subtract 9 on both sides
*4 = 16
cancel the 2 and the 4 using factorization
n*2 = 16
divide 2 on both sides
n = 8
