Question

Which could be the first step in solving the equation represented by the model below?

Answer 1

Answer:

Add 4 positive unit tiles to each side.

Hi hope this helps! brainliest please? :(((((

Step-by-step explanation:

The original equation is:

3x - 4 = 2x + 5

After adding 4 positive unit tiles to each side, we get:

3x - 4 + 4 = 2x + 5 + 4

3x = 2x + 9

which simplifies the original equation, because at the beginning there were independent terms at both sides of the equal sign and now all independent terms are on the right side (the +9 term). Notice that the other options don't give this result

Answer:

Add 4 positive unit tiles to each side.

Answer 2

The answer is A

Explanation-
3x + 4= 2x + 6
-4 = -4
3x=2x + 4
-2x= -2x

X=4
