"the difference between 4 times a number and 3 is 25"

4x+-+3+=+25

where x is some unknown number


Let's solve for x


4x-3=25 Start with the given equation.


4x=25%2B3 Add 3 to both sides.


4x=28 Combine like terms on the right side.


x=%2828%29%2F%284%29 Divide both sides by 4 to isolate x.


x=7 Reduce.
