Question

The incorrect work of a student to solve an equation 2(y + 8) = 4y is shown below:

Step 1: 2(y + 8) = 4y
Step 2: 2y + 10 = 4y
Step 3: 2y = 10
Step 4: y = 5

Group of answer choices

Answer 1

Answer:

Step 2 involved distributive property and the value of y is equal to 8.

Step-by-step explanation:

In step 2, there has been an error in applying the Distributive Property correctly.

Distributive Property-  a(b+c)

                                       = a x b + a x c

Step 2: $2y+16=4y$

Step 3:$2y=16$

Step 4: $y=8$

y=8

Answer 2

Answer:

2 should be distributed as 2y + 16; y + 8
