Find the value of x in the equation 2(x + 4) = 18

Answer 1

2(x + 4) = 18

distribute the 2 to both values in the parentheses

2(x) + 2(4) = 18

2x + 8 = 18

subtract 8 from both sides

2x + 8 -8 = 18 -8

2x + 0 = 10

2x = 10

divide both sides by 2

2x/2 = 10/2

x = 5

to check our answer:

2([5] + 4) = 18

2(9) = 18

18 = 18

our answer is correct!

Answer 2

Hi!

In order to solve this we can use the distributive property to make 2(x+4) into 2x + 8. Putting this equal to 18 we get 2x + 8 = 18. Subtracting 8 from both sides we get 2x = 10, and dividing both sides by 2 we get that x = 5. Hopefully this helps! Let me know if you have any specific questions!
