y=−70

Explanation:

We are given the equation y5=−14=?

In this case we must solve for the unknown variable. Which in this case is y.

To get y by itself, we simply multiply the denominator of the fraction with the opposite side of the equation. See below:

y=−14⋅5.

Simply multiply these together to get your final answer of y=−70.

Now we can substitute −70 in for y. See below for equation:

−705=−14

−14=−14. This verifies we got the right value for y.

Always substitute the unknown value you discover in for an equation like this. You should get the same numerical value on both sides of the equal sign (=). If you don't, then the value is wrong and you simply have to identify what went wrong.

Answer: y=−70
