Question

porfavor ayudeme ..........​

Answer 1

a) 3x + 8 = 2x + 6

3x - 2x = 6 - 8

x = - 2

b) - 2x + 8 = 7

-2x = 7 - 8

-2x = - 1

-2x ÷ - 2 = - 1 ÷ - 2

x = 1/2

c) 3x + 5x = 9

8x = 9

8x ÷ 8 = 9 ÷ 8

x = 9/8

d) 3x/2 = 7

3x = 7 × 2

3x = 14

3x ÷ 3 = 14 ÷ 3

x = 14/3

Answer 2

a.

$3x + 8 = 2x + 6 \\ 3x - 2x = 6 - 8 \\ x = - 2$

b.

$- 2x + 8 = 7 \\ - 2x = - 1 \\ x = \frac{1}{2}$

c.

$3x + 5x = 9 \\ 8x = 9 \\ x = \frac{9}{8}$

d.

$\frac{3x}{2} = 7 \\ 3x = 14 \\ x = \frac{14}{3}$
