QuestionSolve the equation: 3x(x+9)=4x+15+2(x8)3 x - (x + 9) = 4 x + 15 + 2(x - 8).

Studdy Solution

STEP 1

Assumptions1. The given equation is 3x(x+9)=4x+15+(x8)3x - (x +9) =4x +15 +(x -8). We are solving for the variable xx

STEP 2

First, we need to simplify the equation by distributing the negative sign on the left-hand side of the equation.
xx9=4x+15+2(x8)x - x -9 =4x +15 +2(x -8)

STEP 3

Next, simplify the equation by distributing the2 on the right-hand side of the equation.
3xx9=x+15+2x163x - x -9 =x +15 +2x -16

STEP 4

Now, combine like terms on both sides of the equation.
2x9=6x12x -9 =6x -1

STEP 5

Next, we need to isolate xx by subtracting 2x2x from both sides of the equation.
9=4x1-9 =4x -1

STEP 6

Then, add1 to both sides of the equation to further isolate xx.
8=4x-8 =4x

STEP 7

Finally, divide both sides of the equation by4 to solve for xx.
2=x-2 = xSo, the solution to the equation is x=2x = -2.
