Question

3X +5-2 ( 3-X) + 2X = 4+ 2 x (x -1)+5-3


4(x-2) +5X - 6 +8-2x =
X +2-X(4-x)
Como resolver las ecuaciones lineales paso a paso. ​

Answer 1

Explicación paso a paso:

1} 3X + 5 - 2 (3 - X) + 2X = 4 + 2X (X - 1) + 5 - 3

3X + 5 - 6 +2X +2X = 4 + 2X² - 2X + 5 - 3

7X - 1 = 2X² - 2X + 6

0 = 2X² - 9X + 7

2X - 7

1X - 1

0 = (2X - 7) (X - 1)

S¹: 2X - 7 = 0 S²: X - 1 = 0

2X = 7 X = 1

X = 7/2 = 3.5

2} 4 (X - 2) + 5X - 6 + 8 - 2X = X + 2 - X (4 - X)

4X - 8 + 5X - 6 + 8 - 2X = X + 2 - 4X + X²

7X - 6 = X² - 3X + 2

0 = X² - 10X + 8
