23. Given the equation [tex]$y = 2x + 4$[/tex], what would the value of [tex]y[/tex] be when [tex]$x = 1$[/tex]?

A. 1
B. 6
C. 7
D. 5


Sagot :

Certainly! Let's solve for [tex]\( y \)[/tex] when [tex]\( x = 1 \)[/tex] using the given equation [tex]\( y = 2x + 4 \)[/tex].

1. We start with the given equation:
[tex]\[ y = 2x + 4 \][/tex]

2. Substitute [tex]\( x = 1 \)[/tex] into the equation:
[tex]\[ y = 2(1) + 4 \][/tex]

3. Now, perform the multiplication first:
[tex]\[ y = 2 \cdot 1 + 4 \][/tex]
[tex]\[ y = 2 + 4 \][/tex]

4. Finally, perform the addition:
[tex]\[ y = 6 \][/tex]

So, when [tex]\( x = 1 \)[/tex], the value of [tex]\( y \)[/tex] is [tex]\(\boxed{6}\)[/tex].
