Simplify 35x to 3x5

3x5−15=65x+12

2. Simplify 65x to 6x5
3x5−15=6x5+12

3. Multiply both sides by 5
3x−75=6x+60

4. Subtract 3x from both sides
−75=6x+60−3x

5. Simplify 6x+60−3x to 3x+60
−75=3x+60

6. Subtract 60 from both sides
−75−60=3x

7. Simplify −75−60 to −135
−135=3x

8 .Divide both sides by 3
1353=x

9. Simplify 1353 to 45
−45=x

10. Switch sides
x=−45
