First, combine like terms on the left side of the equation:
9x + 9x + 21 = 33
18x + 21 = 33
Next, isolate the variable term:
18x = 33 - 21
18x = 12
Finally, solve for x by dividing both sides of the equation by 18:
x = 12/18
x = 2/3
Therefore, the solution is x = 2/3.
Solve for x.
9x + 9x 21 = 33

Solve for x.
9x + 9x 21 = 33
x = 6
x = 3
x = 8
x = 1
9x + 9x 21 = 33
x = 6
x = 3
x = 8
x = 1
The equation is 9x + 9x + 21 = 33.
Combining like terms on the left side, we have 18x + 21 = 33.
Next, we isolate the variable term by subtracting 21 from both sides:
18x = 33 - 21.
18x = 12.
Finally, we solve for x by dividing both sides of the equation by 18:
x = 12/18.
Reducing the fraction, we get x = 2/3.
Therefore, the correct solution is x = 2/3.
