3(x+5)
In this expression, we cannot perform any operation within the parentheses so we move to the next operation in the expression which is multiplication.
3(x+5)
becomes:
3x + 3(5)
3x + 15
We need to look for the value of x.
3x + 15 = 0
3x = -15
3x/3 = -15/3
x = -5
We need to substitute x by its value.
3(x + 5)
3(-5 + 5)
we can perform the P in PEMDAS
3(0) = 0
multiply.
3(0) = 0
0 = 0
Rule of zero. any number multiplied by zero is equal to zero.
