Solve 8x+(-5x-9)=3x+[-5x-(x+3)]

$$8 x + ( - 5 x - 9 ) = 3 x + [ - 5 x - ( x + 3 ) ]$$

Solve for x

$$x=1$$

Steps for Solving Linear Equation

Combine 8x and -5x to get 3x.

$$3x-9=3x-5x-\left(x+3\right)$$

Combine 3x and -5x to get -2x.

$$3x-9=-2x-\left(x+3\right)$$

To find the opposite of x+3, find the opposite of each term.

$$3x-9=-2x-x-3$$

Combine -2x and -x to get -3x.

$$3x-9=-3x-3$$

Add 3x to both sides.

$$3x-9+3x=-3$$

Combine 3x and 3x to get 6x.

$$6x-9=-3$$

Add 9 to both sides.

$$6x=-3+9$$

Add -3 and 9 to get 6.

$$6x=6$$

Divide both sides by 6.

$$x=\frac{6}{6}$$

Divide 6 by 6 to get 1.

$$x=1$$
