Answer:

To solve for x in the equation 189=-6x+3(-7x-18), we can use the following steps:

Distribute the 3 to the terms inside the parentheses:

189 = -6x + (-21x - 54)

Combine like terms on the right side of the equation:

189 = -27x - 54

Add 54 to both sides of the equation:

189 + 54 = -27x

Simplify the left side of the equation:

243 = -27x

Divide both sides by -27:

x = -9

Therefore, x is equal to -9.

Hope This Helps!

Answer:

x = -9

Explanation:

To solve for x in this equation, we first need to simplify the right-hand side by distributing the 3:

189 = -6x + (-21x - 54)

Next, we can combine like terms on the right-hand side:

189 = -27x - 54

Adding 54 to both sides:

243 = -27x

Dividing both sides by -27:

x = -9

Therefore, the solution to the equation 189=-6x+3(-7x-18) is x = -9.
