Evaluate the following expresion: 3x + 6 - y when x = 2 and y = 5
To evaluate the expression 3x + 6 - y when x = 2 and y = 5, substitute the given values of x and y into the expression:
3(2) + 6 - 5
Simplifying further:
6 + 6 - 5 = 12 - 5 = 7
Therefore, the value of the expression 3x + 6 - y when x = 2 and y = 5 is 7.
To evaluate the expression 3x + 6 - y when x = 2 and y = 5, you substitute the given values into the expression and solve.
Step 1: Replace x with 2:
3(2) + 6 - y
Step 2: Replace y with 5:
3(2) + 6 - 5
Step 3: Simplify the expression:
6 + 6 - 5
Step 4: Perform the addition:
12 - 5
Step 5: Subtract:
7
Therefore, the value of the expression 3x + 6 - y when x = 2 and y = 5 is 7.
To evaluate the expression 3x + 6 - y, substitute the given values of x and y into the expression and compute the result.
Given:
x = 2
y = 5
Substituting the values into the expression:
3(2) + 6 - 5
Simplifying the expression:
6 + 6 - 5
Now, perform the addition and subtraction:
12 - 5 = 7
Therefore, when x = 2 and y = 5, the expression 3x + 6 - y evaluates to 7.
