Starting with
-x%2F7+%2B+5+=+10
2 Options to start
...
Option 1
Multiply the entire equation by 7 to be rid of the fraction
1cross%287%29-x%2F1cross%287%29+%2B+7%285%29+=+7%2810%29
-x + 35 = 70
-x = 70 - 35
-x = 35
Divide both sides by -1
highlight_green%28x=-35%29
...
Option 2
Isolate x
-x%2F7+=+10+-+5
-x%2F7+=+5
Now mulitply both sides by 7
1cross%287%29-x%2F1cross%287%29+=+7%285%29
-x = 35
Divide both sides by -1
highlight_green%28x=-35%29
