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.
