Answer 2

To solve the equation 2*(-2x + 18) = 5x - 18, follow these steps:

Step 1: Distribute the 2 on the left side of the equation. Step 2: Simplify both sides of the equation. Step 3: Isolate x on one side of the equation.

Let's go through each step in detail:

Step 1: Distribute the 2 on the left side of the equation: 2 * (-2x + 18) = 2 * -2x + 2 * 18 -4x + 36 = -4x + 36

Step 2: Simplify both sides of the equation: -4x + 36 = -4x + 36

Step 3: Isolate x on one side of the equation: To isolate x, we need to get rid of the -4x term on the right side of the equation. However, as you can see, the equation already has -4x on both sides, which means the variable x is canceled out, and we are left with:

36 = 36

Since the equation simplifies to a true statement (36 = 36), this means that the original equation is an identity, and there is no unique solution for x. Any value of x will satisfy the equation, making it an infinite number of solutions.

Therefore, the solution to the equation is that x can be any real number.
