How do you solve 3x equals 15?
3x = 15 >> 3x = multiplication, and the opposite of multiplication is division. So you take 3x, draw a line under it to show division, then write 3. After that, cross out the 3x/3. With algebra what you do to one side, you do to the other, so then you take 3 and divide it by 15. >>the answer>> X=5
