Question

for the two variable equation y=3x+4, find the matching y value when x=3

Answer 1

To find the matching \( y \) value for the equation \( y = 3x + 4 \) when \( x = 3 \), substitute \( 3 \) for \( x \):

\[
y = 3(3) + 4
\]
\[
y = 9 + 4
\]
\[
y = 13
\]

So, when \( x = 3 \), the matching \( y \) value is \( 13 \).
