Step-by-step explanation:
Hello!
First, let's write an equation for the problem.

Now, all you have to do is solve it.

=
16Each side is 16 meters. I hope this helps!

Step-by-step explanation:
1) Collect like terms.

2) Simplify.

So, therefor, the answer is -17y - 16z + 4.

First, solve the parentheses:

Next, the exponential terms

Solve the multiplication:

Add and subtract:
70% is the same as 70/100 then we simplify by taking off one zero of each number 7/10 and we can't divide it any more so the answer is 7/10
