Answer 2

I can help you solve the equation -6(9-5x)=9x+9. Here are the steps:

- First, we need to expand the parentheses by multiplying -6 with each term inside. This gives us -54+30x=9x+9. - Next, we need to collect the terms with x on one side and the constants on the other. To do this, we can subtract 9x from both sides and add 54 to both sides. This gives us 21x=63. - Finally, we need to isolate x by dividing both sides by 21. This gives us x=3.

Therefore, the solution of the equation is x=3. You can check this by plugging it back into the original equation and verifying that both sides are equal.
