Question 782278: three times the sum of a number and 2 is 9 less than 8 times the number

You can put this solution on YOUR website!
x = the number

3(x + 2) = 8x - 9 {three times the sum of a number and 2 equals 9 less than the number}
3x + 6 = 8x - 9 {used distributive property}
6 = 5x - 9 {subtracted 3x from each side}
5x = 15 {added 9 to each side}
x = 3 {divided each side by 5}

the number is 3
