Solve for x. 9x+9x−21=33 (1 point) Responses x = 6 x = 6 x = 3 x = 3 x = 8 x = 8 x = 1

Answer 1

To solve for x in the equation 9x + 9x - 21 = 33, first combine like terms on the left side of the equation.

We have 18x - 21 = 33.

Next, isolate x by adding 21 to both sides of the equation.

18x = 54.

Finally, divide both sides of the equation by 18 to solve for x.

x = 3.

Therefore, x = 3.
