Explanation:
what is the problem ? don't you understand what variables are ? they are placeholders for actual values.
therefore, you need to put the given numbers into the places of their variables, and then calculate.
9x + 4y = 9×4 + 4×-3 = 36 - 12 = 24
that's it.
Answer: 48
Step-by-step explanation: If x equals 4, then you would multiply 9 times 4, which is 36.
If y equals 3, then you would multiply 4 times 3, which is 12.
Add these two products together and you get a sum of 48.
