Question

Is this the right answer please help?

Answer 1

Yes! 19 is the correct answer for this problem. When we substitute in our numbers for the variables, we can first start inside the parentheses.

11 - 3z = 11 - 6 = 5

Then, we add the values of x and y together to get 5 + 14 = 19.

Answer 2

Answer:

yes its correct, but you should show your work clearly step by step (see below)

Step-by-step explanation:

My advise would be to NOT skip steps, work each step out methodically and you can get the answer:

(11-3z) + x + y

when x = 9, y = 5 and z = 2,

=[11 - 3(2)  ]  + 9 + 5    Evaluate parentheses (PEDMAS)

=[11 - 6  ]  + 9 + 5

=5  + 9 + 5

=19
