solve equation 3(k-4.8)=0.7(k-6.9) show steps to solve this please

  • math - ,

    3(k-4.8)=0.7(k-6.9)

    3*k-3*4.8=0.7*k-0.7*6.9

    3k - 14.4 = 0.7k - 4.83

    Subtracting 0.7k from each side:

    3k -0.7k - 14.4 = 0.7k - 0.7k - 4.83

    2.3k - 14.4 = -4.83

    Adding 14.4 to each side

    2.3k = 9.57

    Dividing each side by 2.3:

    k = 4.16
