Q. Solve for

x

:

\newline

3+9 x=6.9-(x-2.7)+6.7 x

\newline

Answer:

x=

Simplify equation by distributing: First, simplify the equation by distributing the negative sign inside the parentheses on the right side of the equation. $3 + 9x = 6.9 - x + 2.7 + 6.7x$
Combine like terms: Combine like terms on the right side of the equation. $\newline$ $3 + 9x = 6.9 + 2.7 + 6.7x - x$
Add and combine terms: Add $6.9$ and $2.7$ to get $9.6$ . $\newline$ $3 + 9x = 9.6 + 6.7x - x$
Combine x terms: Combine the $x$ terms on the right side of the equation. $3 + 9x = 9.6 + (6.7 - 1)x$
Calculate difference: Calculate $6.7 - 1$ to get $5.7$ . $\newline$ $3 + 9x = 9.6 + 5.7x$
Subtract $x$ terms: Subtract $5.7x$ from both sides of the equation to get all $x$ terms on one side. $\newline$ $3 + 9x - 5.7x = 9.6$
Combine $x$ terms: Combine the $x$ terms on the left side of the equation. $3 + (9 - 5.7)x = 9.6$
Calculate difference: Calculate $9 - 5.7$ to get $3.3$ . $\newline$ $3 + 3.3x = 9.6$
Subtract to isolate $x$ : Subtract $3$ from both sides of the equation to isolate the term with $x$ . $3.3x = 9.6 - 3$
Calculate difference: Calculate $9.6 - 3$ to get $6.6$ . $\newline$ $3.3x = 6.6$
Divide to solve for $x$ : Divide both sides of the equation by $3.3$ to solve for $x$ . $x = \frac{6.6}{3.3}$
Calculate division: Calculate $6.6 / 3.3$ to get $2$ . $\newline$ $x = 2$
