Question

you’re saying 2x+3=4x+9 has the smallest (closest to zero) possible solution. How do you know for sure?

Answer 1

To solve the equation 2x+3=4x+9, rearrange it to isolate the variable x. The solution is x = 3.

Step-by-step explanation:

We can solve the equation 2x+3=4x+9 by rearranging it to isolate the variable x.

Step 1: Subtract 2x from both sides to isolate the variable x: 3 = 2x - 4x + 9

Step 2: Simplify the equation: 3 = -2x + 9

Step 3: Subtract 9 from both sides: -6 = -2x

Step 4: Divide both sides by -2 to solve for x: x = 3
