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.
