Answer 1

Answer:

Yep. He's right!

Step-by-step explanation:

3x - 4 = 2(x + 3) + x

→ 3x - 4 = 2x + 6 + x

→ 3x - 4 = 3x + 6

→ 3x - 3x = 10

→ 0 ≠ 10

Since we couldn't find a particular value of x, thus this equation has infinite solutions. So, your Hai is right ✓

Answer 2

Answer:

Hai is wrong.

Step-by-step explanation:

Hai's teacher writes the equation 3x-4=2(x+3)+x

Now the solution would be

3x-4=2(x+3)+x

or, 3x-4=2x+6+x

or, 3x-3x=10

or, 0=10

Now this proves that this is not an equation .

As it is not an equation, so it does not have a value that equal in both sides.

Therefore, Hai is wrong, this equation does not have any infinity solutions.
