Solve:
4%282a-a%29+=+%281%2F7%29%2849a%2B70%29 Simplify the left side of the equation.
4a+=+%281%2F7%29%2849a%2B70%29 Now apply the distributive property to the right sides.
4a+=+7a%2B10 Subtract 4a from both sides.
0+=+3a%2B10 Subtract 10 from both sides.
-10+=+3a Finally, divide both sides by 3.
a+=+-10%2F3 or
a = 3 1/3 or a = 3.333...
