Question

7-(3,1-0,1у)=3-0,2у pleaSEEEEEEEEEEEEEEEE

Answer 1

7-(3,1-0,1у)=3-0,2у; 7-3,1+0,1у=3-0,2у; 0,3у= -0,9; у= -3.

Answer 2

To solve the equation 7 - (3.1 - 0.1y) = 3 - 0.2y, let's simplify the expression step by step:

Step 1: Distribute the negative sign to the terms inside the parentheses: 7 - 3.1 + 0.1y = 3 - 0.2y

Step 2: Combine like terms on both sides of the equation: 3.9 + 0.1y = 3 - 0.2y

Step 3: Move all terms containing y to one side and constant terms to the other side: 0.1y + 0.2y = 3 - 3.9

Step 4: Simplify the equation: 0.3y = -0.9

Step 5: Divide both sides of the equation by 0.3 to solve for y: y = -0.9 / 0.3

Step 6: Calculate the result: y = -3

Therefore, the solution to the equation is y = -3.
