Question

6,7+8+(-2,43y)=9+6,7−6,43y

Answer 1

4у=9-8+6.7-6.7
4у=1
у=0.25

Answer 2

Let's solve the equation step by step.

Given equation: 6.7 + 8 + (-2.43y) = 9 + 6.7 - 6.43y

Step 1: Combine like terms on both sides of the equation. On the left-hand side, combine 6.7 and 8: 6.7 + 8 = 14.7

On the right-hand side, combine 9 and 6.7: 9 + 6.7 = 15.7

Step 2: The equation now becomes: 14.7 - 2.43y = 15.7 - 6.43y

Step 3: Move the terms containing 'y' to one side of the equation by adding 2.43y to both sides: 14.7 - 2.43y + 2.43y = 15.7 - 6.43y + 2.43y

Step 4: Simplify the equation: 14.7 = 15.7 - 4y

Step 5: Move the constant term to the other side by subtracting 15.7 from both sides: 14.7 - 15.7 = -4y

Step 6: Simplify the equation: -1 = -4y

Step 7: Solve for 'y' by dividing both sides by -4: y = -1 / -4

Step 8: Final answer: y = 0.25
