Question

2,7 y плюс 3,4y минус 1,2y равно 18,62

Answer 1

2,7 у + 3,4 у - 1,2 у = 18,62
4,9 у = 18,62
у = 186,2 : 49

Ответ: у = 3,8. Удачи!

Answer 2

To solve the equation, we need to combine like terms on the left side and isolate the variable "y." Let's do the math step by step:

Step 1: Combine the "y" terms on the left side of the equation: 2.7y + 3.4y - 1.2y = (2.7 + 3.4 - 1.2)y = 4.9y

Step 2: Now, we have the equation: 4.9y = 18.62

Step 3: To solve for "y," divide both sides of the equation by 4.9: y = 18.62 / 4.9 y ≈ 3.8041

So, the value of "y" that satisfies the equation is approximately 3.8041.
