Astudent is attempting to isolate the variable x in the literal equation below. which statement best applies to the sample
mathematical work shown?
given: 3 (x+2)
step 1: 1 distribute the left-hand side of the equation, resulting in 3x + 2 = y.
step 2: / subtract 2 from both sides, resulting in 3x = y
y-2
step 3: / divide both sides by 3, resulting in * =
3
2 thus, t =
a. the student failed to distribute properly in step 1.
| b. the student failed to subtract both sides correctly in step
c. the division in step 3 is invalid.
d. the mathematical work is correct as written
