Solve 8x-4*4x-8*-4x+4=4x-9

$$8 x - 4 \cdot 4 x - 8 \cdot - 4 x + 4 = 4 x - 9$$

Solve for x

$$x=-\frac{13}{20}=-0.65$$

Steps for Solving Linear Equation

Multiply 4 and 4 to get 16.

$$8x-16x-8\left(-4\right)x+4=4x-9$$

Combine 8x and -16x to get -8x.

$$-8x-8\left(-4\right)x+4=4x-9$$

Multiply 8 and -4 to get -32.

$$-8x-\left(-32x\right)+4=4x-9$$

The opposite of -32x is 32x.

$$-8x+32x+4=4x-9$$

Combine -8x and 32x to get 24x.

$$24x+4=4x-9$$

Subtract 4x from both sides.

$$24x+4-4x=-9$$

Combine 24x and -4x to get 20x.

$$20x+4=-9$$

Subtract 4 from both sides.

$$20x=-9-4$$

Subtract 4 from -9 to get -13.

$$20x=-13$$

Divide both sides by 20.

$$x=\frac{-13}{20}$$

Fraction \frac{-13}{20} can be rewritten as -\frac{13}{20} by extracting the negative sign.

$$x=-\frac{13}{20}$$
