    Hello!

    Solve for x:

    4 (2x+25) = 20

    Distribute the 4 to the numbers inside the parenthesis.

    8x + 100 = 20

    Subtract 100 from both sides of the equation to get 8x by itself.

    8x = - 80

    Divide both sides by 8

    x = - 10

    -10

    Step-by-step explanation:

    simplify both sides of the equation.

    4 (2x+25) = 20

    (4) (2x) + (4) (25) = 20

    8x+100=20

    subtract 100 from both sides.

    8x+100 _100 = 20_100

    8x=-80

    divide both sides by 8

    8x=-80

    8 8

    x=-10
