Answer 2

2*(x+3)-(-5x+1)=7+(3x-4)
4x=-2
х=4:(-2)
x= -2.

Answer 3

To solve the equation 2*(x+3)-(-5x+1) = 7+(3x-4), follow these steps:

Step 1: Distribute the terms inside the parentheses. Step 2: Simplify the expression on both sides of the equation. Step 3: Combine like terms on both sides of the equation. Step 4: Isolate the variable (x) on one side of the equation. Step 5: Solve for x.

Let's go through the steps:

Step 1: 2*(x+3) - (-5x+1) = 7 + (3x-4)

Expanding the parentheses: 2x + 23 - (-5x) - 1 = 7 + 3x - 4

Step 2: Simplify the expression on both sides: 2x + 6 + 5x - 1 = 7 + 3x - 4

Step 3: Combine like terms on both sides: (2x + 5x) + (6 - 1) = 7 + 3x - 4

7x + 5 = 7 + 3x - 4

Step 4: Isolate the variable (x) on one side of the equation. To do this, we'll move the 3x term to the left side and the constant terms to the right side.

Subtract 3x from both sides: 7x - 3x + 5 = 7 - 4

4x + 5 = 3

Step 5: Now, we'll solve for x.

Subtract 5 from both sides: 4x + 5 - 5 = 3 - 5

4x = -2

Finally, divide by 4 to isolate x: x = -2 / 4

x = -1/2

So the solution to the equation is x = -1/2.
