Math Problem Statement

9 ( x - 4 ) = 2 ( x + 3 )

Solution

To solve the equation 9(x4)=2(x+3)9(x - 4) = 2(x + 3), follow these steps:

  1. Distribute the 9 and the 2: 9x36=2x+69x - 36 = 2x + 6

  2. Move all terms involving xx to one side of the equation and constants to the other side. Subtract 2x2x from both sides: 9x2x36=69x - 2x - 36 = 6 Simplify: 7x36=67x - 36 = 6

  3. Add 36 to both sides to isolate the term with xx: 7x36+36=6+367x - 36 + 36 = 6 + 36 Simplify: 7x=427x = 42

  4. Divide both sides by 7 to solve for xx: x=427x = \frac{42}{7} Simplify: x=6x = 6

So, the solution to the equation is x=6x = 6.
