Answer 1

-2,5x-0,6x=-1,1
-3,1x=-1,1
x=11/31

6,5x-2,25x=-9
4,25x=-9
x=-9:(-4,25)
x=36/17
x=2 2/17

Answer 2

To solve the equation 1.1 - 2(1/2)x = 3/5x + 6, we can follow these steps:

Step 1: Distribute the -2 to the terms inside the parentheses: 1.1 - 2(1/2)x = 3/5x + 6 1.1 - x = 3/5x + 6

Step 2: Move the variable terms to one side and the constant terms to the other side: 1.1 - 6 = 3/5x + x -4.9 = 8/5x

Step 3: Simplify the equation: -4.9 = (8/5)x

Step 4: Multiply both sides of the equation by the reciprocal of (8/5), which is (5/8): (-4.9)(5/8) = (8/5)xTo solve the equation 1.1 - 2(1/2)x = 3/5x + 6.5x, we will follow these steps:

Step 1: Simplify the equation by distributing and combining like terms. Step 2: Move all the terms with x to one side of the equation. Step 3: Solve for x.

Let's solve the equation step by step:

Step 1: Simplify the equation

To simplify the equation, we need to distribute the -2 to the terms inside the parentheses:

1.1 - 2(1/2)x = 3/5x + 6.5x 1.1 - x = 3/5x + 6.5x

Next, let's combine like terms on both sides of the equation:

1.1 - x = (3/5 + 6.5)x 1.1 - x = (13/10)x

Step 2: Move all the terms with x to one side of the equation

To move all the terms with x to one side of the equation, we will subtract (13/10)x from both sides:

1.1 - x - (13/10)x = (13/10)x - (13/10)x 1.1 - (23/10)x = 0

Step 3: Solve for x

To solve for x, we will isolate the x term by moving the constant term to the other side of the equation:

1.1 - (23/10)x = 0 1.1 = (23/10)x

To solve for x, we will multiply both sides of the equation by the reciprocal of (23/10), which is (10/23):

(10/23) * 1.1 = (10/23) * (23/10)x 0.4782608695652174 = x

Therefore, the solution to the equation 1.1 - 2(1/2)x = 3/5x + 6.5x is x = 0.4782608695652174.

Please note that the solution is rounded to 16 decimal places for simplicity.
