(k x 4) + m = 4k + m Just put the numbers together with the unknown for products, then put the other parts you need to add behind (think of grouping)
If you want to say "Nine is less than a number k," you would write 9<K. If you're asking for an equation, e.g. "Nine less than a number k is equal to that number divided by three," you would write k - 9.
