Final answer:
To find the value of 3x + 2y, substitute x + y = 4 into the expression. However, without more information we cannot determine the exact value.
Step-by-step explanation:
To find the value of 3x + 2y, we can substitute x + y = 4 into the expression. So, we have: 3x + 2y = 3(x + y) + 2y = 3(4) + 2y = 12 + 2y.
However, we don't have a value for y. Without more information, we cannot determine the exact value of 3x + 2y. We need either the value of y or an equation that relates x and y.
