16x+5=36-15
15x+2=19-5X
9x+8=16+5
18x-3=19+5
11x+8=6x+9. Me las resuelven con procedimiento completo porfavor

Answer 1

Explicación paso a paso:

$13x + 8 = 2x + 20 \\ 13x - 2x = 20 - 8 \\ 11x = 12 \\ x = \frac{12}{11}$

$16x + 5 = 36 - 15 \\ 16x = 36 - 15 - 5 \\ 16x = 16 \\ x = \frac{16}{16} \\ x = 1$

$15x + 2 = 19 - 5x \\ 15x + 5x = 19 - 2 \\ 20x = 17 \\ x = \frac{17}{20}$

$9x + 8 = 16 + 5 \\ 9x = 16 + 5 - 8 \\ 9x = 13 \\ x = \frac{13}{9}$

$18x - 3 = 19 + 5 \\ 18x = 19 + 5 + 3 \\ 18x = 27 \\ x = \frac{27}{18} = \frac{9}{6} = \frac{3}{2} = 1 \frac{1}{2}$

$11x + 8 = 6x + 9 \\ 11x - 6x = 9 - 8 \\ 5x = 1 \\ x = \frac{1}{5}$
