    A x=3.1

    Step-by-step explanation:

    1/2 (4x+6) = -5x+24.7

    Multiply each side by 2 to get rid of the fraction

    2*1/2 (4x+6) = 2 (-5x+24.7)

    4x+6 = - 10x + 49.4

    Add 10x to each side

    4x+6+10x=-10x+10x+49.4

    14x + 6 = 49.4

    Subtract 6 from each side

    14x+6-6 = 49.4-6

    14x = 43.4

    Divide each side by 14

    14x/14 = 43.4/14

    x = 3.1
