Answer: X = 4
Step-by-step explanation: To solve for k in this equation, we want to get k by itself on the left side of the equation.
Since k is being multiplied by 5, to get k by itself, we need to divide by 5 on the left side of the equation. Since we divided by 5 on the left side, we must also divide by 5 on the right side.
On the left side, notice that the 5's cancel out, so we are simply left with z. On the right side, we have 20 divided by 5 which gives us 4.
Now we have X = 4.
Finally, remember to check your answer by substituting a 4 back into the original equation.
So we have 5 (4) = 20 which is a true statement.
This means that our answer, x = 4 is correct.

I hope this helps you
Area=width×length
161=width×14
width=161/14
width =11,5
40 square inches
