    x=27

    Step-by-step explanation:

    5 multiplied by x=5x

    5 times 3 = 15

    so 5x+15

    4 times x = 4x

    4 times - 3 = - 12

    so 5x+15=4x-12

    move 4x next to 5x

    move 15 next to - 12

    5x-4x=-12-15

    (remember when you transpose a positive number it becomes a negative and vice versa!)

    x=-27
