Solve 4x − 2(x + 1) = 3x + 10. −12 12 −8 8
Dominik [7]
Original Equation: 4x - 2(x+1) = 3x + 10

Step 1: Use Distributive Property
4x - 2x - 2 = 3x + 10

Step 2: Combine Like Terms
2x - 2 = 3x + 10

Step 3: Solve
       2x - 2 = 3x + 10
     - 2x        -2x 
--------------------------------
      -2 = x + 10
    -10         -10
------------------------
    -12 = x

2/3(6c+4)-(8c-5) Please explain how to do the problem.
irga5000 [103]
2/3(6c+4)-(8c-5)
1) Get rid of the negative signs
New equation (the ones in bold are the changes): 2/3(6c+4)+(-8c)+(5)
2) Use distributive property for the first part by multiplying 2/3*6c= 4c and 2/3*4= 2 2/3
New equation: 4c+2 2/3+ (-8c) + 5
3) Combine like terms: 4c+(-8c)= -4c and 2 2/3+5= 7 2/3
New and simplified equation: -4c+ 7 2/3

How do you us the distributive property to work out (4+5)6
777dan777 [17]
During Distributive property, the number on the outside of the parenthesis basically gets multiplied by the numbers inside the parenthesis. In this case, you would multiply 6 by 5 and 4. When you get the products, then follow the sign that comes next. In this case, you would add the products to get a total sum. I attached a photo for further reference.
Hope this helps!
