Question

If 4x+y=7 is a true equation what would be the value of −5(4x+y)

Answer 1

40x - 5y = -40x - 5(4x + y) = -40x - 20x - 5(7) = -60x - 35

Explanation:

To find the value of -5(4x+y), we first need to simplify the expression inside the parentheses:

-5(4x + y) = -5(4x) - 5(y) = -20x - 5y

Now, we can substitute the value of y from the given equation:

-20x - 5y = -20x - 5(4x + y) = -20x - 20x - 5y = -40x - 5y

Since we know that 4x + y = 7, we can substitute this into the above equation:

-40x - 5y = -40x - 5(4x + y) = -40x - 20x - 5(7) = -60x - 35

Answer 2

-32

Explanation:

since 4x+y equals 7, multiply -5 by 7
