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]
