Solve:
3a%2F4+%2B+7%2F6+=+-a+%2B+7%2F24 Multiply through by 24 to clear the fractions.
24%283a%2F4%29+%2B+%2824%297%2F6+=+24%28-a%29+%2B+%2824%297%2F24 Simplify.
18a+%2B+28+=+-24a+%2B+7 Add 24a to both sides of the equation.
42a+%2B+28+=+7 Subtract 28 from both sides.
42a+=+-21 Finally, divide both sides by 42.
a+=+-21%2F42
a+=+-1%2F2
