    Distribute out the 2 28=8w-22+9 28=8w-13 add 13 to both sides 28+13 = 8w 41=8w divide both sides by 8 5.125 = w

    28=2 (4w-11) + 9

    Step 1: Expand the brackets by multiplying what's in them by 2.

    28=8w-22+9

    Step 2: Simplify the constants on the right side - 22 and 9 by adding them.

    28=8w-13

    Step 3: Add 13 to both sides to isolate the variable.

    41=8w

    Step 4: Divide both sides by 8 to isolate the variable completely.

    x=41/8

    Leave the answer in a fraction form 41/8 or a decimal form 5.125.
