Question

8 less than a number 7 times a number is the same as 4 more than 3 times the number. Find the number

Answer 1

X=3

7x-8=3x+4
4x=12
x=3

Answer 2

7n-8=3n+4. You subtract 3n in both sides and get 4n-8=4. then you add 8 to both sides and get 4n=12. Finally you divide both sides by 4 too get n by itself. n=3
