Question

evaluate the following expression for x= 3 , y = 2, and z=2 the expression is 5y(7z-x)

Answer 1

5y(7z - x)

5(2) (7(2) - 3)
10(14 - 3)
140 - 30
110

There is another way to do this, I believe, but unless I find a mistake, this is my answer. You just have to insert the value of the variables.
