The equation 4(x+3) = 0 has to be solved for x.
4(x+3) = 0
=> x + 3 = 0
=> x = -3
The solution of 4(x+3) = 0 is x = -3.

Due to the zero product principle, this problem has 1 answer.
The zero-product principle says that when multiplying two or more terms to get 0, one (or more) must equal zero.
4 can never equal zero, so in this case, the (x+3) must equal zero.
It is simple to solve this:
x+3=0 Subtract 3 from both sides and...
x=-3 Voila!
x=-3 is your answer.

4(x+3) = 0
Distribute the 4 to the x and the 3. (Multiply)
4x+12=0
Subtract 12 on both sides to isolate the variable.
4x=-12
Divide both sides by 4 to isolate x.
x=-3

4(x+3) = 0
Distribute 4
4x + 12 =0
subtract 12
4x = -12
divide by 4
x = -3

4(x+3) = 0
Distribute the 4:
4x + 12 =0
subtract the 12:
4x = -12
divide by 4
x = -3

You are solving for x but it says it equals to 0, well because of that you need to distribute the variable first
4(x+3) = 0
4x+12=0
Now instead of the 0 you can move the 12 over to isolate the variable
then divide by 4
x=-3

4 ( x + 3 ) = 0
First distribute
By distributing, your equation should look like
4x + 12 = 0 now subtract 12 on both sides to get " x " alone
By subtracting, your equation should look like
4x = -12 Now divide 4 on both sides
By dividing, your equation will look like
x = -3 which is your answer

4 (x + 3) = 0
We know that either the left factor or the right factor has to equal zero. Since 4 can never equal zero, we only have to set x + 3 = 0
Solving for x, we get that x = -3.
