Answer
$12$
Work Step by Step
Convert all the x values to fractions with a common denominator so they can be combined. Then move the values so all the x's are on the same side of the equation.
$(3x/6)+(8x/6)-(6x/6)=10$
Multiply both sides by the reciprocal (6/5) and reduce to an integer.
$5x/6=10$
$x=12$
