wat is the solution to the following equaton?

4(4n + 7) = -20

4(4n + 7)= -20
16n + 28= -20
16n= -20 - 28
16n= -48
n= -48/16
n= -3

To solve the equation 4(4n + 7) = -20, you can follow these steps:

Step 1: Distribute the 4 on the left side of the equation.

4 * 4n + 4 * 7 = -20

16n + 28 = -20

Step 2: Combine like terms on the left side of the equation.

16n + 28 = -20

Step 3: Subtract 28 from both sides of the equation.

16n = -20 - 28

16n = -48

Step 4: Divide both sides of the equation by 16 to isolate n.

n = -48 / 16

Simplifying the division gives:

n = -3

So the solution to the equation 4(4n + 7) = -20 is n = -3.
