Solve for all values of x in simplest form. 4+|5x+4|=7 Answer: x=

Write Given Equation: Write down the given equation. We have the equation 4 + |5x + 4| = 7. We need to find the value of x that satisfies this equation.Isolate Absolute Value: Isolate the absolute value expression. Subtract 4 from both sides of the equation to isolate the absolute value on one side. 4 + |5x + 4| - 4 = 7 - 4 |5x + 4| = 3Set Up Two Equations: Set up two separate equations to account for the absolute value. Since the absolute value of a number can be either positive or negative, we have two cases: Case 1: 5x + 4 = 3 Case 2: 5x + 4 = -3Solve Case 1: Solve for x in Case 1. Subtract 4 from both sides of the first case equation. 5x + 4 - 4 = 3 - 4 5x = -1 Now, divide both sides by 5 to solve for x. x = -1 / 5Solve Case 2: Solve for x in Case 2. Subtract 4 from both sides of the second case equation. 5x + 4 - 4 = -3 - 4 5x = -7 Now, divide both sides by 5 to solve for x. x = -7 / 5

in simplest form.

4+|5 x+4|=7

\newline

Answer:

x=

Write Given Equation: Write down the given equation. $\newline$ We have the equation $4 + |5x + 4| = 7$ . $\newline$ We need to find the value of $x$ that satisfies this equation.
Isolate Absolute Value: Isolate the absolute value expression. $\newline$ Subtract $4$ from both sides of the equation to isolate the absolute value on one side. $\newline$ $4 + |5x + 4| - 4 = 7 - 4$ $\newline$ $|5x + 4| = 3$
Set Up Two Equations: Set up two separate equations to account for the absolute value. $\newline$ Since the absolute value of a number can be either positive or negative, we have two cases: $\newline$ Case $1$ : $5x + 4 = 3$ $\newline$ Case $2$ : $5x + 4 = -3$
Solve Case $1$ : Solve for $x$ in Case $1$ . $\newline$ Subtract $4$ from both sides of the first case equation. $\newline$ $5x + 4 - 4 = 3 - 4$ $\newline$ $5x = -1$ $\newline$ Now, divide both sides by $5$ to solve for $x$ . $\newline$ $x = -\frac{1}{5}$
Solve Case $2$ : Solve for $x$ in Case $2$ . $\newline$ Subtract $4$ from both sides of the second case equation. $\newline$ $5x + 4 - 4 = -3 - 4$ $\newline$ $5x = -7$ $\newline$ Now, divide both sides by $5$ to solve for $x$ . $\newline$ $x = -7 / 5$
