i'm not sure if you mean 25% <em>off</em> or 25% <em>of</em> so i'll just do both
25% <em>OFF</em>: $150
25% <em>OF</em>: $50
3x+1/10=x-1/7
subtract 1/10 from both sides
3x=-1/7-1/10+x
subtract x from both sides
2x=-1/7-1/10
add -1/7 and -1/0
1/7=10/70
1/10=7/70
-10/70-7/70=-17/70
2x=-17/70
divide by 2 ro multiply by 1/2
x=-17/140
