Brandon used inverse operations to solve an equation in his homework assignment. during which step, if any at all, did
brandon use the incorrect inverse operation to isolate the variable?
equation: 8x3 + 2 = 26
brandon's solution:
step 1:
8x + 2 = 26
-2 -2 (subtract 2 from each side.)
bk
= 24
(divide each side by 8.)
8° 24
step 2:
x=3
x 3
step 3: 33
x=1
(divide each side by 3.)
step 1
step 2
step 3
all of the inverse operations were correct
