Answer 2

To solve the equation (2x-5) - (3x-7) = 4, we can simplify the expression and combine like terms:

First, let's distribute the negative sign to the terms inside the second parentheses:

(2x-5) - 3x + 7 = 4

Next, combine the like terms:

2x - 5 - 3x + 7 = 4

Now, let's simplify further by combining the x terms:

(2x - 3x) + (-5 + 7) = 4

-x + 2 = 4

To isolate x, we need to get rid of the 2 on the left side. We can do this by subtracting 2 from both sides of the equation:

-x + 2 - 2 = 4 - 2

-x = 2

Finally, to solve for x, we multiply both sides of the equation by -1 to get x by itself:

x = -2

Therefore, the solution to the equation (2x-5) - (3x-7) = 4 is x = -2.
