Solve for x : 4-(-x-4)=4+9x Answer: x=

Distribute negative sign: Simplify the left side of the equation by distributing the negative sign. 4 - (-x - 4) = 4 + 9x 4 + x + 4 = 4 + 9x Combine like terms on the left side. (4 + 4) + x = 4 + 9x 8 + x = 4 + 9xCombine like terms: Subtract 4 from both sides to isolate the variable terms. 8 + x - 4 = 4 + 9x - 4 4 + x = 9xIsolate variable terms: Subtract x from both sides to get all x terms on one side. 4 + x - x = 9x - x 4 = 8xGet x terms on one side: Divide both sides by 8 to solve for x. 4 / 8 = 8x / 8 1/2 = x

Q. Solve for

x

\newline

4-(-x-4)=4+9 x

\newline

Answer:

x=

Distribute negative sign: Simplify the left side of the equation by distributing the negative sign. $\newline$ $4 - (-x - 4) = 4 + 9x$ $\newline$ $4 + x + 4 = 4 + 9x$ $\newline$ Combine like terms on the left side. $\newline$ $(4 + 4) + x = 4 + 9x$ $\newline$ $8 + x = 4 + 9x$
Combine like terms: Subtract $4$ from both sides to isolate the variable terms. $\newline$ $8 + x - 4 = 4 + 9x - 4$ $\newline$ $4 + x = 9x$
Isolate variable terms: Subtract $x$ from both sides to get all $x$ terms on one side. $\newline$ $4 + x - x = 9x - x$ $\newline$ $4 = 8x$
Get $x$ terms on one side: Divide both sides by $8$ to solve for $x$ . $\frac{4}{8} = \frac{8x}{8}$ $\frac{1}{2} = x$
