$5x - 3.4 = 16$

$3(x + 2.6) = 24$

$\frac{x}{3} - 1.8 = 1.4$
​

Answer 1

Respuesta y Explicación paso a paso:

1.

5x - 3.4 = 16

5x = 16 + 3.4

5x = 19.4

x = 19.4/5

x = 3.88

2.

3(x + 2.6) = 24

3x + 7.8 = 24

3x = 24 - 7.8

3x = 16.2

x = 16.2/3

x = 5.4

3.

$\frac{x}{3}$ - 1.8 = 1.4

$\frac{x}{3}$ = 1.4 + 1.8

$\frac{x}{3}$ = 3.2

x = 3.2 * 3

x = 9.6
