<h2>Add 4 positive unit tiles to each side.</h2><h2>Hi hope this helps! brainliest please? :(((((</h2>
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
175 students walk to school. 7+5=12 and 420 divided by 12 is 35. I checked how I did it was correct because of 5*35+7*35=420. Then I found the product of 5*35 which is 175.
