Let's start with the given equation and the provided value for \( x \):
[tex]\[ 5x + 2y = 20 \][/tex]
Given:
[tex]\[ x = 0.3 \][/tex]
First, substitute \( x = 0.3 \) into the equation:
[tex]\[ 5(0.3) + 2y = 20 \][/tex]
Now, perform the multiplication:
[tex]\[ 1.5 + 2y = 20 \][/tex]
Next, isolate \( 2y \) by subtracting 1.5 from both sides of the equation:
[tex]\[ 2y = 20 - 1.5 \][/tex]
Simplify the subtraction:
[tex]\[ 2y = 18.5 \][/tex]
Finally, solve for \( y \) by dividing both sides by 2:
[tex]\[ y = \frac{18.5}{2} = 9.25 \][/tex]
Therefore, the value of \( y \) when \( x = 0.3 \) is \( 9.25 \).
So, the correct answer is:
[tex]\[ y = 9.25 \][/tex]
