7x over 5 = 42 over 3

Answer 1

Let's see if any reductions can be made before solving for x.

7x/5 = 42/3

42/3 can be reduced to 14/1 or just 14.

Now you have:

7x/5 = 14

Multiply both sides by 5 to get rid of the denominator. Whatever operation you do to one side of an equation you must do to the other side as well.

7x/5 * 5 = 14 * 5

7x = 70

x = 10

Check this answer with the original equation. It always helps to check your work!
