Math Problem Statement

3x-5-2(-x+9)=2

Solution

Let's solve the equation 3x52(x+9)=23x - 5 - 2(-x + 9) = 2.

Step 1: Distribute the -2 on the left-hand side

3x52(x+9)=3x5+2x18=23x - 5 - 2(-x + 9) = 3x - 5 + 2x - 18 = 2 This simplifies to: 5x23=25x - 23 = 2

Step 2: Add 23 to both sides to isolate the term with xx

5x23+23=2+235x - 23 + 23 = 2 + 23 5x=255x = 25

Step 3: Divide by 5 to solve for xx

x=255=5x = \frac{25}{5} = 5

Thus, the solution is x=5x = 5.
