Answer:
x = -2
Step-by-step explanation:
2(3x + 9) = 0
You multiply everything inside the brackets by 2
6x + 18 = 0
Now, make the variables in one side and the numbers in the other side.
It becomes: 6x = 0 - 18
6x = -18
Just so you remember:
6x = 6 • x
And the opposite of multiplication is division
so it becomes: x = -18 / 6
x = -3
CHECK:
Let x = -3
2[3(-3) + 9] = 0
2(-9 + 9) = 0
2 • 0 = 0
0 = 0
