Answer:

x = 4

Step-by-step explanation:

1.3x - 10 = 0.8x - 8

start by getting all like terms to the same side

subtract 0.8 x from both sides, add 10 to both sides

0.5x = 2

divide both sides by 0.5

x = 4

Answer:

x = 4

Step-by-step explanation:

1.3x - 10 = 0.8x - 8

Add 10 to both sides.

1.3x = 0.8x + 2

Subtract 0.8x from both sides.

0.5x = 2

Divide by 0.5.

x = 4.

Proof:

1.3x - 10 = 0.8x - 8

1.3(4) - 10 = 0.8(4) - 8

5.2 - 10 = 3.2 - 8

-4.8 = -4.8

Divide using synthetic division: (2x^4+2x^3+-12x^2+x+6)/(x+3)

kap26 [50]

Synthetic division yields

..... || 2 2 -12 1 6

-3 || -6 12 0 -3

= = = = = = = = = = = = = =

..... || 2 -4 0 1 3

which translates to

$\dfrac{2x^4+2x^3-12x^2+x+6}{x+3}=2x^3-4x^2+1+\dfrac3{x+3}$
