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
