Solve for x : 2.8=-1-2.5(-x+6.2) Answer: x=

Distribute -2.5: Which operation should be used to simplify the equation? First, distribute the -2.5 across the parentheses. -2.5 * -x + -2.5 * 6.2 = 2.5x - 15.5Add 1 to both sides: What is the next step to isolate x? Add 1 to both sides to move the constant term from the right side to the left side. 2.8 + 1 = 2.5x - 15.5 + 1 3.8 = 2.5x - 15.5Add 15.5 to both sides: What should be done next to solve for x? Add 15.5 to both sides to get all the x terms on one side and the constants on the other. 3.8 + 15.5 = 2.5x 19.3 = 2.5xDivide by 2.5: How do we isolate x completely? Divide both sides by 2.5 to solve for x. 19.3 / 2.5 = x x = 7.72

x

\newline

2.8=-1-2.5(-x+6.2)

\newline

Answer:

x=

Distribute $-2.5$ : Which operation should be used to simplify the equation? $\newline$ First, distribute the $-2.5$ across the parentheses. $\newline$ $-2.5 \times -x + -2.5 \times 6.2 = 2.5x - 15.5$
Add $1$ to both sides: What is the next step to isolate $x$ ? $\newline$ Add $1$ to both sides to move the constant term from the right side to the left side. $\newline$ $2.8 + 1 = 2.5x - 15.5 + 1$ $\newline$ $3.8 = 2.5x - 15.5$
Add $15$ . $5$ to both sides: What should be done next to solve for x? $\newline$ Add $15.5$ to both sides to get all the $x$ terms on one side and the constants on the other. $\newline$ $3.8 + 15.5 = 2.5x$ $\newline$ $19.3 = 2.5x$
Divide by $2$ . $5$ : How do we isolate $x$ completely? $\newline$ Divide both sides by $2.5$ to solve for $x$ . $\newline$ $19.3 / 2.5 = x$ $\newline$ $x = 7.72$
