You can put this solution on YOUR website!
You can let x = the number of math problems on Tim's homework assignment.
You can set up the equation as follows:
%282%2F3%29x+=+12 Solve for x by multiplying both sides by the multiplicative inverse of 2/3, which is 3/2
x+=+12%283%2F2%29
x+=+18
Tim had 18 problems on his math homework assignment.
