Question

Look at the equation below. How many solutions are there?

2(3x+4)=6x+8)

Answer 1

Answer:14x

Explanation:

3x+4=7x

7x times 2 = 14

6x+8=14x

Answer 2

x∈R

Explanation:

2(3x+4)=6x+8

Use the distributive property to multiply 2 by 3x+4.

6x+8=6x+8

Subtract 6x from both sides.

6x+8−6x=8

Combine 6x and −6x to get 0.

8=8

Compare 8 and 8.

True

This is true for any x.

x∈R
