Step-by-step explanation:
The result of the expression is 69.2
The expression is given as:
2x - yz2x−yz
The values of the variables are given as:
x = 34x=34
y = -0.2y=−0.2
z = 6z=6
Substitute these values in the given expression.
So, we have:
2x - yz = 2 \times 34 -(-0.2) \times 62x−yz=2×34−(−0.2)×6
Evaluate the products
2x - yz = 68+ 1.22x−yz=68+1.2
2x - yz = 69.22x−yz=69.2
Hence, the result of the expression is 69.2
