Question

Evaluate |2x+y-3z| for x=-2, y=10, and z=3
How to solve?

Answer 1

the answer is (3) because when all the letters are turned into numbers then solved it becomes [-4+10+(-9)] then you have to turn it into a positive because of the lines.

Answer 2

|2x + y - 3z|
Plug in the values
|-4 + 10 - 9|
= |-3|
= 3
