Step-by-Step Solution

Let's solve the equation 34(x2)=6x+4(3x) 3-4(x-2)=6x+4(3-x) .

First, apply the distributive property on both sides:

  • For the left side: 34(x2) 3 - 4(x - 2) becomes 34x+8 3 - 4x + 8 , which simplifies to 114x 11 - 4x .
  • For the right side: 6x+4(3x) 6x + 4(3 - x) becomes 6x+124x 6x + 12 - 4x , which simplifies to 2x+12 2x + 12 .

Now the equation is:

114x=2x+12 11 - 4x = 2x + 12

Combine like terms to isolate x x . First, move all terms containing x x to one side and constant terms to the other side:

  • Add 4x 4x to both sides: 11=6x+12 11 = 6x + 12 .
  • Subtract 12 from both sides: 1112=6x 11 - 12 = 6x , which simplifies to 1=6x -1 = 6x .

Finally, solve for x x by dividing both sides by 6:

x=16 x = -\frac{1}{6} .

Therefore, the solution to the problem is x=16 x = -\frac{1}{6} , which corresponds to choice 4.

Answer

16 -\frac{1}{6}
