Dalia Decker · Answer 1

Subtract 6.4 from 42.5 so you can get 3.5n by itself.

42.5-6.4=36.1

then since you now have 3.5n by itself you are goin to divide 36.1 by 3.5

36.1/3.5=10.31

so n=10.31

Kamari Barrera · Answer 2

The first step to solving your equation would be to subtract 6.4 from both sides.

3.5n+6.4=42.5

Subtract 6.4

3.5n=42.5
