Rephrase the problem: First, let's rephrase the problem into a clear ＂What is the value of x in the equation 80 = (880 + 20x) / (-0.30)?＂Multiply by -0.30: To solve for x, we should start by multiplying both sides of the equation by -0.30 to get rid of the fraction. 80 * (-0.30) = (880 + 20x) / (-0.30) * (-0.30)Perform left side multiplication: Now, let's perform the multiplication on the left side of the equation. -24 = 880 + 20xIsolate the term with x: Next, we need to isolate the term with x. To do this, we subtract 880 from both sides of the equation. -24 - 880 = 880 + 20x - 880Divide by 20: After performing the subtraction, we get the following equation. -904 = 20xFind the value of x: Now, to solve for x, we divide both sides of the equation by 20. -904 / 20 = 20x / 20Finally, we perform the division to find the value of x. x = -904 / 20 x = -45.2

80=\frac{880+20 x}{30}

Rephrase the problem: First, let's rephrase the problem into a clear ＂What is the value of $x$ in the equation $80 = (880 + 20x) / (-0.30)$ ?＂
Multiply by $-0.30$ : To solve for $x$ , we should start by multiplying both sides of the equation by $-0.30$ to get rid of the fraction. $\newline$ $80 \times (-0.30) = (880 + 20x) / (-0.30) \times (-0.30)$
Perform left side multiplication: Now, let's perform the multiplication on the left side of the equation. $\newline$ $-24 = 880 + 20x$
Isolate the term with x: Next, we need to isolate the term with x. To do this, we subtract $880$ from both sides of the equation. $\newline$ $-24 - 880 = 880 + 20x - 880$
Divide by $20$ : After performing the subtraction, we get the following equation. $\newline$ $-904 = 20x$
Find the value of x: Now, to solve for $x$ , we divide both sides of the equation by $20$ . $-904 / 20 = 20x / 20$
Find the value of x: Now, to solve for $x$ , we divide both sides of the equation by $20$ .
$-904 / 20 = 20x / 20$ Finally, we perform the division to find the value of $x$ .
$x = -904 / 20$
$x = -45.2$
