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 ctivity
