Solve for x: −2(3x−15)−4=56.

Answer 1

To solve the equation, we will begin by distributing -2 to the terms inside the parentheses:

-2(3x - 15) - 4 = 56

Multiply -2 by 3x:

-6x + 30 - 4 = 56

Combine like terms:

-6x + 26 = 56

Next, we will isolate -6x by subtracting 26 from both sides of the equation:

-6x + 26 - 26 = 56 - 26

-6x = 30

Finally, we will solve for x by dividing both sides of the equation by -6:

-6x/(-6) = 30/(-6)

x = -5
