Question

2 solve 4(-5x + 15) = 40.

Explanation:

Step1: Divide both sides by 4

To isolate the expression inside the parentheses, we divide both sides of the equation \(4(-5x + 15) = 40\) by 4.

$$ \frac{4(-5x + 15)}{4}=\frac{40}{4} $$

Simplifying both sides, we get \(-5x + 15 = 10\).

Step2: Subtract 15 from both sides

To isolate the term with \(x\), we subtract 15 from both sides of the equation \(-5x + 15 = 10\).

$$ -5x + 15 - 15=10 - 15 $$

Simplifying both sides, we have \(-5x=-5\).

Step3: Divide both sides by -5

To solve for \(x\), we divide both sides of the equation \(-5x = -5\) by \(-5\).

$$ \frac{-5x}{-5}=\frac{-5}{-5} $$

Simplifying both sides gives \(x = 1\).

Answer:

\(x = 1\)
