Answer 3

Solving Equation A: (2x-1)+(-x+5)=2

To solve the equation (2x-1)+(-x+5)=2, we can simplify the equation by combining like terms and then isolate the variable x.

Let's simplify the equation step by step:

(2x-1)+(-x+5)=2

First, let's remove the parentheses:

2x - 1 - x + 5 = 2

Next, let's combine like terms:

(2x - x) + (-1 + 5) = 2

x + 4 = 2

Now, let's isolate the variable x by subtracting 4 from both sides of the equation:

x + 4 - 4 = 2 - 4

x = -2

Therefore, the solution to equation A is x = -2.

Solving Equation B: (43-12x)-(-7x+33)=-2

To solve the equation (43-12x)-(-7x+33)=-2, we can simplify the equation by removing the parentheses and then isolate the variable x.

Let's simplify the equation step by step:

(43-12x)-(-7x+33)=-2

First, let's remove the parentheses:

43 - 12x + 7x - 33 = -2

Next, let's combine like terms:

(43 - 33) + (-12x + 7x) = -2

10 - 5x = -2

Now, let's isolate the variable x by adding 5x to both sides of the equation:

10 - 5x + 5x = -2 + 5x

10 = 3x

Finally, let's solve for x by dividing both sides of the equation by 3:

10/3 = x

Therefore, the solution to equation B is x = 10/3 or approximately x = 3.33.

I hope this helps! Let me know if you have any further questions.
