The problem asks us to find the value of the variable y given a linear equation and the value of the variable x.
We are given the equation:
$2x + 3y = 23$
And we know that:
$x = 4$
To find y, we substitute the value of x (which is 4) into the given equation:
$2(4) + 3y = 23$
Now, we simplify and solve for y:
$8 + 3y = 23$
$3y = 23 - 8$
$3y = 15$
$y = \frac{15}{3}$
$y = 5$
Therefore, the value of y is 5.
If $2x - 3y = -1$ and $\frac{x}{x+y} = \frac{7}{12}$, then the value of $2xy$ is:
