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.

Darius is asked to solve the equqtion x plus 5 equals 4x over 3?
x + 5 = 4x/3 Solve for x multiply both sides of the equation by 3... 3 * (x + 5) = 3 * (4x/3) 3x + 15 = 4x subtract 3x from both sides of the equation (3x + 15) - 3x = (4x) - 3x 15 = x x = 15
