If you will look at this problem, the greater number is positive integer and smaller number is negative integer, so just subtract smaller from larger one and put that sign before the result which larger integer bears.
You can write it as , - 15 + 32 , and you will get same result.
2. Method: By Marking -15 and 32 on number line
Mark 15 and 32 on number line,start marking circles 1,2,3 from 16 to 31, as there will be 17 circles between 15 to 32, which is the result.
<span><u><em>Proposed statement/question:</em></u> Jonathan has 32 math problems to do by the weekend. On Thursday he completes 15 math problems. How many more math problems does Jonathan need to finish in order to be done before the weekend?
<u><em>The answer to this question would be as follows:</em></u> Total questions to answer is 32 Number of questions answered is 15 Number of questions left is unknown
<u>Therefore:</u> Total questions to answer = questions answered + questions left 32 = 15 + questions left questions left = 32 - 15</span>
Y= -3/5x - 2 Add -3/5x to both sides 3/5x +y= -2 Multiply both sides by 5 because 5 is the denominator. By multiplying by 5 you can cancel out and make it a real number. 5(3/5x +y) = -2(5)
