Question

Найдите ,a/b если 2a + 3b = 4a + 7b.

Answer 1

Ответ:  $\frac{a}{b}=-2$

Объяснение:

$2a+3b=4a+7b\; \; \to \; \; -2a=4b\; ,\; \; a=-2b\; |:b\ne 0\\\\\frac{a}{b}=-2$

Answer 2

To find the value of a/b from the equation 2a + 3b = 4a + 7b, we need to solve for the values of a and b. Let's do that step by step:

1. Move all terms involving a to one side of the equation and all terms involving b to the other side:

   2a + 3b = 4a + 7b

   Subtract 2a from both sides:

   2a - 2a + 3b = 4a - 2a + 7b

   3b = 2a + 7b - 2a

2. Combine like terms:

   3b = 5b

3. Now, we can see that the variable b disappears, which means it can be any value. Let's assume b = 1.

   3 * 1 = 5 * 1

   3 = 5

   Since the equation is not true when b = 1, it means there is no unique solution for a/b in this case. The value of a/b is indeterminate.
