    The answer is x = 12/7

    because you multiply 15 by x to get 15x

    15x = 4 (2x+3)

    next you simplify the right side by using the distributive property by doing 15x = 4 (2x) + 4 (3)

    Then you multiply 2 by 4 to get 8

    15x = 8x + 4 (3)

    and multiply 4 by 3 to get 12

    15x = 8x + 12

    Now you move terms containing (x) to the left side of the equation.

    Since 8x contains the variable to solve for, move it to the left side of the equation by subtracting 8x from both sides.

    15x - 8x = 12

    subtract 8x from 15x to get 7x

    7x = 12

    Also, divide each term by 7 and simplify

    Divide each term in 7x = 12 by 7

    7x/7 = 12/7

    Lastly, reduce the expression by cancelling the common factors by

    crossing out all 7s 7x/7 and leave 12/7 as it is, and divide x by 1 to get x by

    x = 12/7

    So the answer is x = 12/7
