Work out the Greatest Common Factor for both numbers
54 42
1×54 1×42
2×27 2×21
3×18 3×14
6×9 6×7
The common factors are: 1, 2, 3 and 6
The greatest common factor is 6
There are 6 identical arrangements that can be made
X + 7/6 = 2x - 7/6
x + 7/6 (-7/6) = 2x - 7/6 - (7/6)
x = 2x - 14/6
x (-2x) = 2x (-2x) - 14/6
-x = -14/6
x = 14/6 or 2.33
x = 2.33
hope this helps
