Evaluate the expression when x=10,y=-2,andz=-5.
2zy
Step 1: On substituting value of y and z in given expression 2zy we get,
=2(-5)-2
Step 2: =-10-2=+5
(The quotient of integers with the same signs is negative)
Final Answer: The expression is +5.
Evaluate the expression 5x+7y-8z+12, when x=2,y=3,z=4.
