Solve for x: 20x - 5(6x + 15) = - 45

Question

x = 2
x = - 2
X = -3
x = 3

Answer 1

The correct solution is x = -3.

To solve for x, we first distribute the -5 to both terms inside the parentheses:

20x - 30x - 75 = -45

Combine like terms:

-10x - 75 = -45

Add 75 to both sides:

-10x = 30

Divide by -10:

x = -3

So, x = -3.
