Solve for x: 20x−5(6x+15)=−45

Answer 1

To solve for x in the given equation, we will first expand the brackets:

20x - 5(6x + 15) = -45
20x - 30x - 75 = -45

Next, we simplify by combining like terms:

-10x - 75 = -45

Then, we add 75 to both sides of the equation:

-10x = 30

Finally, we can solve for x by dividing both sides of the equation by -10:

x = -3

Therefore, the solution to the given equation is x = -3.
