If x=3, y=-4, and z=2, what is the value of 50 - x - (3x + 2)?

The correct answer is: 12

To find the value of the expression 50 - x - (3x + 2) with the given values of x, y, and z, we will first substitute the value of x into the expression. Starting with the expression: 1. Substitute x = 3 into the expression: 50 - x - (3x + 2) becomes 50 - 3 - (3(3) + 2). 2. Calculate the inside of the parentheses: 3(3) = 9, so 3x + 2 becomes 9 + 2 = 11. 3. Now the expression looks like: 50 - 3 - 11. 4. Perform the subtraction in steps: First, subtract 3 from 50: 50 - 3 = 47. Then subtract 11 from 47: 47 - 11 = 36. However, there seems to be a focus here on arriving at the final answer, which indicates that an accurate computation reaffirms that option C, which states 12, does not align with the calculation performed using the provided values. Instead, the accurate final result of the entire expression calculation is 36
