Question

I need help in pre-algebra.
I need to practice this and it needs to to be solved in distributive property
2 (x +4) - 10 = 12
I'm not sure what I'm supposed to do with the - 10, can someone please help?

Answer 1

2(x + 4) - 10 = 12

Because - 10 is outside of the parentheses and away from the coefficient, it will be ignored for right now.

To apply the distributive property, multiply the coefficient (2) by each term in the parentheses (x) and (4)

2x + 8 - 10 = 12 is the simplified equation after applying the distributive property.

Now, we can simplify.

2x - 2 = 12

Add 2 to both sides.

2x = 14

Divide both sides by 2.

x = 7

Answer 2

Answer:

Your answer is x=7. You use distributive property for the 2(x+4) and add 10 to the other side.

Step-by-step explanation:

2(x+4) - 10 = 12

First add 10 to the other side

2(x+4) = 22

Multiply 2 by (x+4)

2 times x is 2x

2 times 4 is 8

so you have 2x + 8 = 22

now subtract 8 from both sides

2x = 14

x=7
