Question

Select all the equations that are equivalent to 1/2(4+8x)=17.

1. 2+4x=8.5
2. 4x=15
3. 4+8x=8.5
4. 4+8x=34
5. 2=17-8x

Answer 1

4x=15

Explanation:

1/2(4+8x)=17. You divide everything inside the parentheses in half. So the new equation is 2+4x=17. You could combine like factors. So minus the two from the 17 to get 4x by itself. Now you have 4x=15
