Question

(40,2+х):(-2,5)=-113/5

Answer 1

(40,2+х):(-2,5) = -113/5

(40,2+х)*5 = -113*(-2,5)

201 + 5х = 282,5

5х = 282,5 - 201

5х = 81,5

х= 81,5/5 = 16,3

Проверка

(40,2+х):(-2,5) = -113/5

(40,2+16,3) : (-2,5) = -113/5

56,5 / (-2,5) = -113/5

56,5 * 5 = -113 * (-2,5)

282,5 = 282,5

Answer 2

To solve the equation (40 + 2x) / (-2.5) = -113/5, we can first simplify the equation by multiplying both sides by -2.5 to eliminate the denominator:

(-2.5) * (40 + 2x) / (-2.5) = (-2.5) * (-113/5)

This simplifies to:

40 + 2x = 22.6

Next, we can isolate the term with x by subtracting 40 from both sides of the equation:

40 + 2x - 40 = 22.6 - 40

This simplifies to:

2x = -17.4

Finally, we can solve for x by dividing both sides of the equation by 2:

2x / 2 = -17.4 / 2

This simplifies to:

x = -8.7

Therefore, the solution to the equation (40 + 2x) / (-2.5) = -113/5 is x = -8.7.
