Answer

x = \frac{12}{7}

Step-by-step solution

4 steps

Distribute the numbers into the parentheses.
$3(2x - 1) - (2 - x) = 7$ $6x - 3 - 2 + x = 7$
Combine like terms on the left side of the equation.
$(6x + x) + (-3 - 2) = 7$ $7x - 5 = 7$
Add 5 to both sides of the equation to isolate the term with $x$ .
$7x - 5 + 5 = 7 + 5$ $7x = 12$
Divide both sides by 7 to solve for $x$ .
$\frac{7x}{7} = \frac{12}{7}$ $x = \frac{12}{7}$
