Question

A⋅d=b⋅c):0,1y+4=0,9y−7. Y=​

Answer 1

Ответ:

У=13,75

Пошаговое объяснение:

0,1у+4=0,9у-7

0,1у-0,9=-7-4

-0,8у=-11

У=13,75

Answer 2

To solve the equation (A⋅d=b⋅c): 0.1y + 4 = 0.9y - 7, you need to isolate y on one side of the equation. Here's the step-by-step solution:

1. Get all the terms with y on one side and the constant terms on the other side: 0.1y - 0.9y = -7 - 4

2. Combine like terms: -0.8y = -11

3. Divide both sides by -0.8 to solve for y: y = -11 / -0.8

4. Simplify the right-hand side: y = 13.75

So, the solution to the equation is y = 13.75.
