Question

Susan begins counting backward from 1298 by 4's, saying one number every 5 seconds. At the same time, Jim begins counting forward from 171 by 3's, saying one number every 5 seconds. What number will they both say at the same time?

Answer 1

I think the answer might be 654

Answer 2

 The answer is 654 
1298-4x=171+3x
1127-4x=3x
1127=7x
161=x now plug this in to the original equations 1298-4(161)=171 + 3(161)
                                                                            1298-644    =171 + 483
                                                                                654         = 654
