I got -5
correct
To solve this equation, you need to simplify both sides of the equation by distributing and combining like terms.
Let's start by distributing the -5 and the 5 to the terms inside the parentheses on the left side of the equation:
-5(1-5x) + 5(-8x-2) = -4x - 8x
Applying the distributive property, we get:
-5 * 1 + (-5 * -5x) + 5 * -8x + 5 * -2 = -4x - 8x
Simplifying further:
-5 + 25x - 40x - 10 = -4x - 8x
Next, we can combine like terms on both sides of the equation:
-5 - 10 + (25x - 40x) = -4x - 8x
Simplifying further:
-15 + (-15x) = -12x
Now, to isolate the variable x, let's move the -15 to the right side of the equation by adding 15 to both sides:
-15 + 15 + (-15x) = -12x + 15
This simplifies to:
-15x = -12x + 15
Finally, to solve for x, let's move the -12x to the left side of the equation by adding 12x to both sides:
-15x + 12x = 15
Simplifying further:
-3x = 15
To solve for x, divide both sides by -3:
(-3x)/(-3) = 15/(-3)
This gives us the final answer:
x = -5
