Answer 1

1) To solve the equation 3.2y - 0.6 = 2.7y + (1.1y - 0.2) + 0.8, we can start by simplifying the equation.

First, let's simplify the right side of the equation: 2.7y + (1.1y - 0.2) + 0.8 = 2.7y + 1.1y - 0.2 + 0.8 = 3.8y + 0.6

Now, the equation becomes: 3.2y - 0.6 = 3.8y + 0.6

Next, let's isolate the variable y on one side of the equation. We can do this by subtracting 3.2y from both sides: 3.2y - 3.2y - 0.6 = 3.8y - 3.2y + 0.6 -0.6 = 0.6y + 0.6

To isolate y, we can subtract 0.6 from both sides: -0.6 - 0.6 = 0.6y + 0.6 - 0.6 -1.2 = 0.6y

Finally, we can solve for y by dividing both sides by 0.6: -1.2 / 0.6 = 0.6y / 0.6 -2 = y

Therefore, the solution to the equation 3.2y - 0.6 = 2.7y + (1.1y - 0.2) + 0.8 is y = -2.

2) To solve the equation 2.1x + 0.4 = 3.1x - (1.1x + 0.4) + 0.6, we can follow a similar process.

First, let's simplify the right side of the equation: 3.1x - (1.1x + 0.4) + 0.6 = 3.1x - 1.1x - 0.4 + 0.6 = 2x + 0.2

Now, the equation becomes: 2.1x + 0.4 = 2x + 0.2

Next, let's isolate the variable x on one side of the equation. We can do this by subtracting 2x from both sides: 2.1x - 2x + 0.4 = 2x - 2x + 0.2 0.1x + 0.4 = 0.2

To isolate x, we can subtract 0.4 from both sides: 0.1x + 0.4 - 0.4 = 0.2 - 0.4 0.1x = -0.2

Finally, we can solve for x by dividing both sides by 0.1: 0.1x / 0.1 = -0.2 / 0.1 x = -2

Therefore, the solution to the equation 2.1x + 0.4 = 3.1x - (1.1x + 0.4) + 0.6 is x = -2.
