Question

2,7y+3,4y-1,2y=18,62

Answer 1

2,7y+3,4у-1,2у=18,62
4,9у=18,62
у=18,62 : 4,9
у = 3,8

Answer 2

4.9y=18.62
y=18.62:4.9
y=3.8

Answer 3

To solve the equation 2.7y + 3.4y - 1.2y = 18.62, we can combine like terms on the left side and then isolate the variable y.

Let's simplify the equation step by step:

2.7y + 3.4y - 1.2y = 18.62

(2.7 + 3.4 - 1.2) y = 18.62 [Combining the y terms]

4.9y - 1.2y = 18.62

3.7y = 18.62 + 1.2

3.7y = 19.82

Now, we can isolate y by dividing both sides of the equation by 3.7:

y = 19.82 / 3.7

y ≈ 5.35

Therefore, the solution to the equation 2.7y + 3.4y - 1.2y = 18.62 is y ≈ 5.35.
