Question

23,3 -(2,3а+1,2а)=19,3​

Answer 1

Ответ:

Пошаговое объяснение:

23,3 -(2,3а+1,2а)=19,3​

3,5а = 23,3 - 19,3

3,5а = 4

а = 4 : 3,5

а= 4 : 3 5/10

а= 4 * 10/35

а= 8/7 = 1 1/7

Answer 2

To solve the equation, let's simplify the expression on the left side and then isolate the variable 'a'.

Given equation: 23.3 - (2.3a + 1.2a) = 19.3

First, let's combine like terms within the parentheses: 23.3 - (2.3a + 1.2a) = 19.3 23.3 - 3.5a = 19.3

Next, let's isolate the variable 'a' by moving the constants to the other side of the equation: 23.3 - 3.5a = 19.3 -3.5a = 19.3 - 23.3 -3.5a = -4

To solve for 'a', divide both sides of the equation by -3.5: (-3.5a) / -3.5 = -4 / -3.5 a = 4 / 3.5

Simplifying the right side: a = 1.1428571428571428

Therefore, the value of 'a' that satisfies the equation 23.3 - (2.3a + 1.2a) = 19.3 is approximately a = 1.1428571428571428.
