Answer 2

To solve the equation 5x - 7 = 5(x - 2) + 3, we will start by simplifying both sides of the equation.

First, let's distribute the 5 on the right side:

5x - 7 = 5x - 10 + 3

Next, we can combine like terms on the right side:

5x - 7 = 5x - 7

Notice that both sides of the equation have the same expression, 5x - 7. This means that the equation is an identity, and the solution is all real numbers. In other words, any value of x will satisfy the equation.

Therefore, the solution to the equation 5x - 7 = 5(x - 2) + 3 is x ∈ ℝ (all real numbers).
