Question

11,3y-(9,7-0,8y)+7,4=17

Answer 1

11.3y-(9.7y-0.8y)+7.4=17

11.3y-8.9y+7.4=17

2.4y+7.4=17

2.4y=17-7.4

2.4y=9.6

24y=96 (:24)

y=4

Answer 2

To solve the equation 11.3y - (9.7 - 0.8y) + 7.4 = 17, you can follow these steps:

1. First, distribute the negative sign through the parentheses: 11.3y - 9.7 + 0.8y + 7.4 = 17

2. Combine like terms on both sides of the equation. Combine the y terms and the constants separately: (11.3y + 0.8y) - (9.7 - 7.4) = 17

3. Simplify the expressions within the parentheses: 12.1y - 2.3 = 17

4. To isolate the variable y, add 2.3 to both sides of the equation: 12.1y = 17 + 2.3 12.1y = 19.3

5. Finally, divide both sides by 12.1 to solve for y: y = 19.3 / 12.1 y ≈ 1.595

So, the solution to the equation is approximately y ≈ 1.595.
