    x = - 30/7

    Step-by-step explanation:

    6x + 5 (2x + 7) = 9x + 5

    Distribute

    6x + 10x + 35 = 9x+5

    Combine like terms

    16x + 35 = 9x+5

    Subtract 9x from each side

    16x-9x + 35 = 9x-9x+5

    7x + 35 = 5

    Subtract 35 from each side

    7x+35-35 = 5-35

    7x = - 30

    Divide each side by 7

    7x/7 = - 30/7

    x = - 30/7

    Step-by-step explanation:

    Solve 6x + 5 (2x + 7) = 9x + 5

    Isolate x (on the left) and solve for x

    6x+10x+35 = 9x + 5 [ do not forget to distribute 5 to the 7]

    6x+10x-9x=5-35

    7x=-30

    x=-30/7

    or in mixed fraction

    x=-4 2/7
