Question

38 × a = 1,9 + b = 2,24 ÷ c = 56

Answer 1

38 * а = 1,9 + b = 2,24 : с = 56
с = 2,24 : 56 = 0,04
b = 2,24 - 1,9 = 0,34
а = 1,9 : 38 = 0,05
---------------------------------------------
38 * 0,05 = 1,9 + 0,34 = 2,24 : 0,04 = 56 

Answer 2

To solve for the variables a, b, and c in the given equation, we need to isolate each variable on one side of the equation and simplify the expression as much as possible.

38 × a = 1.9 + b ...(1)

2.24 ÷ c = 56 ...(2)

Let's start with equation (1):

38 × a = 1.9 + b

Subtracting 1.9 from both sides, we get:

38 × a - 1.9 = b

So we have:

b = 38 × a - 1.9 ...(3)

Now, let's move on to equation (2):

2.24 ÷ c = 56

Multiplying both sides by c, we get:

2.24 = 56c

Dividing both sides by 56, we get:

c = 2.24 ÷ 56

Simplifying, we get:

c = 0.04 ...(4)

Now, we can substitute equation (3) and (4) into the original equation to solve for a:

38 × a = 1.9 + b

38 × a = 1.9 + (38 × a - 1.9) (Substituting equation (3))

Simplifying, we get:

38a = 38a

This equation is true for any value of a. Therefore, a can take any value.

So the solution to the equation 38 × a = 1.9 + b = 2.24 ÷ c = 56 is:

a can take any value b = 38 × a - 1.9 c = 0.04
