Answer :

To solve the problem, let's follow the given steps:

1. Given:
[tex]\( x = 7 \)[/tex]
[tex]\( y = 5x - 4 \)[/tex]

2. Step 1:
Substitute [tex]\( x = 7 \)[/tex] into the equation [tex]\( y = 5x - 4 \)[/tex].

[tex]\[ y = 5(7) - 4 \][/tex]

3. Step 2:
Calculate the multiplication inside the equation.

[tex]\[ 5 \times 7 = 35 \][/tex]

4. Step 3:
Substitute the result of the multiplication back into the equation.

[tex]\[ y = 35 - 4 \][/tex]

5. Step 4:
Perform the subtraction.

[tex]\[ 35 - 4 = 31 \][/tex]

Therefore, the value of [tex]\( y \)[/tex] is:

[tex]\[ \boxed{31} \][/tex]
