Answer :

To evaluate the expression [tex]\(3y + 9 - 2x\)[/tex] given the values [tex]\(x = 4\)[/tex] and [tex]\(y = 2\)[/tex], follow these steps:

1. Substitute the given values of [tex]\(x\)[/tex] and [tex]\(y\)[/tex] into the expression:

[tex]\[ 3(2) + 9 - 2(4) \][/tex]

2. First, perform the multiplication for both terms:

[tex]\[ 3 \cdot 2 = 6 \][/tex]
[tex]\[ 2 \cdot 4 = 8 \][/tex]

3. Substitute these results back into the expression:

[tex]\[ 6 + 9 - 8 \][/tex]

4. Then, perform the addition and subtraction from left to right:

[tex]\[ 6 + 9 = 15 \][/tex]
[tex]\[ 15 - 8 = 7 \][/tex]

Therefore, the value of the expression [tex]\(3y + 9 - 2x\)[/tex] when [tex]\(x = 4\)[/tex] and [tex]\(y = 2\)[/tex] is [tex]\(7\)[/tex].
