Question

1)7,5x - 2,46x = 78,3 + 124,56

Answer 1

7,5х-2,45х=78,3+124,56;
5,04х=202,86;
х=202,86÷5,04;
х=40,25;
Ответ:40,25

Answer 2

To solve the given equation $7.5x - 2.46x = 78.3 + 124.56$, first combine the like terms on the left side of the equation:

$5.04x = 202.86$

Now, to solve for $x$, divide both sides of the equation by 5.04:

$x = \frac{202.86}{5.04} = 40.2143$

Therefore, the solution to the equation $7.5x - 2.46x = 78.3 + 124.56$ is $x \approx 40.2143$.
