Answer 1

Ответ:

х=1-3/4

х=1/4

х=4/5+11/5

х=15/5

х=3

2х-5-х+1=0

х-4=0

х=4

2,7х+1,3-х-3=0

1,7х-1,7=0

х=1,7÷1,7

х=1

Answer 2

To solve the equations, let's go through each one step by step:

1. 3/4 + x = 1: To isolate x, we can subtract 3/4 from both sides: x = 1 - 3/4 x = 4/4 - 3/4 x = 1/4

So the solution to the equation is x = 1/4.

2. x - 1 1/5 = 4/5: To solve for x, we can add 1 1/5 to both sides: x = 4/5 + 1 1/5 x = (4/5 + 5/5) + 1/5 x = 9/5 + 1/5 x = 10/5 x = 2

So the solution to the equation is x = 2.

3. 2x - 5 = x - 1: To isolate x, we can subtract x from both sides and add 5 to both sides: 2x - x = -1 + 5 x = 4

So the solution to the equation is x = 4.

4. 2.7x + 1.3 = x + 3: To isolate x, we can subtract x from both sides and subtract 1.3 from both sides: 2.7x - x = 3 - 1.3 1.7x = 1.7 x = 1

So the solution to the equation is x = 1.

Please note that these solutions are obtained by solving the given equations. If you have any specific requirements or doubts, feel free to ask.
