Which of the following is not a step in solving the equation 3/x = 8/7 (1) Divide both sides of the equation by 8(2) Use cross products to write the equation 3.7 =8x(3) Divide both sides of the equation by 3(4) Rewrite 3.7 as 21

Sagot :

Let's solve the equation:

3/x = 8/7

8x = 3 * 7 Cross product

8x = 21 Rewrite 3 * 7 as 21

Dividing both sides by 8:

8x/8 = 21/8

x = 2.625

As you can see, we do not follow step 3. Divide both sides of the equation by 3.
