Here is the original equation:
2.4x+%2B+19.2+%3E+48.0+-+7.2x
Now, most kids don't like all the decimals, so move all decimals over to the right by 1 jump. We get
24x+%2B+192+%3E+480+-+72x
step 1 - subtract 192 from both sides to get
24x++%3E+288+-+72x
step 2 - add 72x to both sides to get
96x++%3E+288
step 3 - divide by 96 to get
x+%3E+3
