Question

Eight times the result of subtracting 3 from a number is equal to the number increased by 25. What is the number?

Answer 1

x= the numbers
8(x-3)=x+25
distribute
8x-24=x+25
minus x both sides
7x-24=25
add 24 both sides
7x=49
divide both sides by 7
x=7

the numbers is 7

Answer 2

8(x-3) = x + 25
8x -24 = x + 25
7x = 49
x = 7
