Question

This scale balanced when 17+t=22. Suppose the left side becomes 21+t. How can you change the right side so that 21+t=​___ is equivalent to 17+t=22​? 21+t 22

Answer 1

By adding the difference between the new and original left-side terms to the right side of the original equation, we find that the equation 21+t is equivalent to 26 when balanced.

Step-by-step explanation:

To solve the equivalent equation for 21+t, we need to adjust the right side of the original equation 17+t=22.

The difference between the left sides of the new equation (21+t) and the original equation (17+t) is 4.

Therefore, we add 4 to the right side of the original equation, which would be 22 + 4.

This will keep the scale balanced, so our new equation will be 21+t=26.
