Math Problem Statement

2(x-9)=-2

Solution

To solve the equation 2(x9)=22(x - 9) = -2, follow these steps:

  1. Distribute the 2 on the left-hand side: 2(x9)=2x182(x - 9) = 2x - 18 So the equation becomes: 2x18=22x - 18 = -2

  2. Add 18 to both sides of the equation to isolate the term with xx: 2x18+18=2+182x - 18 + 18 = -2 + 18 This simplifies to: 2x=162x = 16

  3. Divide both sides by 2 to solve for xx: 2x2=162\frac{2x}{2} = \frac{16}{2} Simplifying gives: x=8x = 8

Thus, the solution is x=8x = 8.
