Question

- 21 – 1,7у = 43,8 + 3,7у

Answer 1

Ответ:-12

Пошаговое объяснение:-21-1.7y=43.8+3.7y

-1.7y-3.7y=43.8+21

-5.4y=64.8

y=-12

Answer 2

Ответ:

-12

Пошаговое объяснение:

- 21 – 1,7у = 43,8 + 3,7у

– 1,7у-3,7у = 43,8 + 21

-5,4у=64,8

у=64,8:(-5,4)

у=-12

Answer 3

To solve the equation for y, follow these steps:

Given equation:

21 - 1.7y = 43.8 + 3.7y

Step 1: Combine the y terms on one side of the equation and the constant terms on the other side. You can do this by subtracting 3.7y from both sides and adding 21 to both sides:

21 - 1.7y - 3.7y = 43.8 + 3.7y - 3.7y

Simplify:

21 - 5.4y = 43.8

Step 2: Now, isolate the term with y by subtracting 21 from both sides:

21 - 5.4y - 21 = 43.8 - 21

Simplify:

-5.4y = 22.8

Step 3: Divide both sides by -5.4 to solve for y:

y = 22.8 / -5.4

y ≈ -4.22

So, the solution for the equation is approximately y = -4.22.
