Which equation is equivalent to 3(2×-5)= 4(×+3)

There are infintely many equivalent equations to a given equation.

In fact, every time you perform a legit transformation on your equation, you have an equivalent equation. Legit transformations include, for example, adding/subtracting a same number from both sides, or multiplying/dividing both sides by any non-zero number.

In your case, we can expand the multiplications on both sides:

And these are two equivalent equations.

We can go on solving the equation adding 15 to both sides, and we get

and this is another equivalent equation. Finally, we can subtract 4x from both sides:

and divide both sides by 2:

All the equations we got in this example are equivalent:

are all equivalent.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
