+%28x%2B5%29%2F5-%282x-12%29%2F7=1+ ............both sides multiply by 35 which is divisible with both 5 and 7

35%28x%2B5%29%2F5-35%282x-12%29%2F7=1%2A35

cross%2835%297%28x%2B5%29%2Fcross%285%29-cross%2835%295%282x-12%29%2Fcross%287%29=35

7%28x%2B5%29-5%282x-12%29=35

7x%2B35-10x%2B60=35.............you probably made mistake here when multiply -5 and -12

-3x%2B95=35

95-35=3x

60=3x

60%2F3=x

20=x

You wrote the wrong equation.
You want %28x%2B5%29%2F5-%282x-12%29%2F7=1

LCD 35.
35%28x%2B5%29%2F5-35%282x-12%29%2F7=35
7x%2B35-%2810x-60%29=35
-3x%2B95=35
-3x=35-95
-3x=-60
x=20

You might have made a sign mistake, but not sure without seeing your actual work.
