Answer
x = $\frac{4}{3}$
Or, using set notation.
{x|x = $\frac{4}{3}$}
Work Step by Step
2 + 3(2x - 7) = 9 - 4(3x + 1)
First, use the distributive property as needed:
2 + 6x - 21 = 9 - 12x - 4
Next, combine like terms on each side of the equation. You may want to regroup (on each side of the equation) the terms so that like terms are together. Remember, the sign to the left of a term stays with the term.
2 - 21 + 6x = 9 - 4 - 12x
-19 + 6x = 5 - 12x
Now, add 12x to both sides of the equation.
-19 + 6x + 12x = 5 - 12x + 12x
-19 + 18x = 5 (completing the addition)
Next, add 19 to both sides of the equation.
-19 + 19 + 18x = 5 + 19
18x = 24
Last, divide both sides by 18.
$\frac{18x}{18}$ = $\frac{24}{18}$
Completing the division we get: x = $\frac{24}{18}$ = $\frac{4}{3}$ (in reduced form.)
