Question

0,7(2y - 5) = 0,4(y - 3) - 1,16

Answer 1

Ответ:

1,14

Пошаговое объяснение:

1,4y-3,5=0,4y-1,2-1,16

1y=1,14

Answer 2

To solve the equation 0.7(2y - 5) = 0.4(y - 3) - 1.16, you'll want to simplify and isolate the variable y. Here's how you can do it step by step:

1. Distribute the constants on the right side of the equation:

0.7(2y - 5) = 0.4(y - 3) - 1.16

0.7 * 2y - 0.7 * 5 = 0.4 * y - 0.4 * 3 - 1.16

1.4y - 3.5 = 0.4y - 1.2 - 1.16

2. Now, let's move all terms involving y to one side of the equation and the constants to the other side:

1.4y - 0.4y = 3.5 - 1.2 - 1.16

(1.4y - 0.4y) = (3.5 - 1.2 - 1.16)

1y = 1.14 - 1.2 - 1.16

3. Now, simplify the constants on the right side:

1y = -1.22

4. Finally, divide both sides by 1 to isolate y:

y = -1.22

So, the solution to the equation 0.7(2y - 5) = 0.4(y - 3) - 1.16 is:

y = -1.22
