<h3>For the lowest common multiple you do your times tables.</h3><h3>For example,5,10,15,20,25,30,35,40,45,50.</h3><h3>Those are your times tables of 5.</h3><h3>On the other side do your 6 times tables up to 60.</h3><h3>6,12,18,24,30,36,42,48,54,60.</h3><h3>Now that you have got both,Write down the smallest number in them that they both have.</h3><h3>For example,it would be<u> 30.</u></h3>

This is because that’s the smallest number in the multiple of both numbers.

( x - 7 )/ ( x - 2 ) = 5/4 , Therefore x = -------------

skad [1K]

Answer:

x = -18

Explanation:

To solve this problem easily, we can cross multiply. You would multiply the numerator of the first fraction by the denominator of the second, and multiply the numerator of the second fraction by the denominator of the first. In this case, (x-7) would be multiplied by 4 and 5 would be multiplied by (x-2). The answers from these two calculations would each be one side of the equation.

After doing this, you can solve and isolate x.
