okay so you first need to subtract the two. 2-3 is what?

4. anonymous

-1

5. anonymous

okay so what times seven equals seven?

6. anonymous

1

7. anonymous

exactly. division is the oppisate of multiplication. 1*7=7. so now what do you think x equals?

8. anonymous

7-2=5

9. anonymous

no no

10. anonymous

okay wait.

11. anonymous

what is it then

12. anonymous

the answers given do not make sense with the problem. the answer for x should be seven because 7/1=7 therefore x should be 7 but there isn't that choice so that is kind of confusing.

is the problem $\frac{x}{2}- 3 = 7$?

15. anonymous

x=20

16. anonymous

how did you get that answer?

17. anonymous

is it 5

Let's solve your equation step-by-step. x/2−3=7 Step 1: Simplify both sides of the equation. x/2−3=7 Let's simplify step-by-step. x/2−3=7 1/2x+−3=7 1/2x−3=7 Step 2: Add 3 to both sides. 1/2x−3+3=7+3 1/2x=10 Step 3: Multiply both sides by 2. 2*(1/2x)=(2)*(10) x=20
