Question

2х+3у-z При х=5 у=2 z=3

Answer 1

2×5+3×2-3=12
10+5-3=12

Answer 2

To evaluate the expression 2x + 3y - z when x = 5, y = 2, and z = 3, simply substitute the given values into the expression and perform the arithmetic.

1. Substitute the values: 2(5) + 3(2) - 3

2. Perform the arithmetic: 10 + 6 - 3

3. Final result: 13

So, when x = 5, y = 2, and z = 3, the expression 2x + 3y - z evaluates to 13.
