2x-1=5x+8

3+3x-1=x+2+2x

2 (1+2x)=10

2 (3x-2)=-2

1-x/3=5x/3

2x/3+16/3=-4x/2

1+1/2 (4x-6)=-2

5-2 (1-×)=2x-3

1/2 (4x/3-4)-4=0

Answer 1

Se hacen los respectivos despejes de la incógnita x para hallar su valor:

1)2x-1 = 5x+8

2x-5x = 8+1

-3x = 9

x = $\frac{9}{-3}$

x = -3

2)3+3x-1 = x+2+2x

3x-x-2x = 2-3+1

0x = 0

3)2*(3x-2) = -2

6x-4 = -2

6x = -2+4

6x = 2

x = $\frac{2}{6}$

4)2*(1+2x) = 10

2+4x = 10

4x = 10-2

x = $\frac{8}{4}$

x = 2

5)$\frac{1-x}{3}$ = $\frac{5x}{3}$

1-x = 5x

-x-5x = -1

-6x = -1

x = $\frac{1}{6}$

6)$\frac{2x}{3}$ + $\frac{16}{3}$ = $\frac{-4x}{2}$

$\frac{2x}{3}$ + $\frac{4x}{2}$ = -$\frac{16}{3}$

$\frac{4x+12x}{6}$ = -$\frac{16}{3}$

$\frac{16x}{6}$ = -$\frac{16}{3}$

16x = $\frac{-96}{3}$

7)1 + $\frac{1}{2}$*(4x-6) = -2

1 + 2x-3 = -2

2x = -2-1+3

2x = 0

x = 0

8)5-2*(1-x) = 2x-3

5-2+2x = 2x - 3

3+2x = 2x - 3

0x = -6 (esta ecuación es una incongruencia)

9)$\frac{1}{2}$*($\frac{4x}{3}$-4) = 0

$\frac{4x}{6}$-2 = 0

$\frac{4x}{6}$ = 2

4x = 12

x = $\frac{12}{4}$

x = 3
