Question

X + 35/17 = 4 The answer is 33/17 but I got it wrong because I multiplied 4 by 17. Why do I minus 35/17 from 4 instead of multiplying 17 to four? Do I always minus a positive fraction instead of multiplying the denominator when solving linear equations?

Answer 1

X=33/17

Here is how it works

By the way what you are working with is called improper factions, which is when the big number is placed over the smaller number.

Now 33/17 is also 1 16/17

35/17 is also 2 1/17

Now we can the proper fractions which are 1 16/17 and 2 1/17

1+2=3 and 16/17 + 1/17 equals 1

3+1=4
