ayuda porfavor urjente

Answer 1

Respuesta:

$2(x + 5) = 16 \\ 2x + 10 = 16 \\ 2x = 16 - 10 \\ 2x = 6 \\ x = \frac{6}{2} \\ x = 3$

Solo haré este paso a paso, los demás lo haré de manera directa.

$3(t + 1) = 18 \\ 3t + 3 = 18 \\ 3t = 15 \\ t = 5$

$2(3y - 5) = 14 \\ 6y - 10 = 14 \\ 6y = 24 \\ y = 4$

$4(3t - 2) = 88 \\ 12t - 8 = 88 \\ 12t = 96 \\ t = 8$

$2(3x + 1) = 11 \\ 6x + 2 = 11 \\ 6x = 9 \\ x = \frac{3}{2}$

$6(3k + 5) = 39 \\ 18k + 30 = 39 \\ 18k = 9 \\ k = \frac{1}{2}$

$9(3x - 5) = 9 \\ 27x - 45 = 9 \\ 27x = 54 \\ x = 2$

$3(t + 7) = 15 \\ 3t + 21 = 15 \\ 3t = - 6 \\ t = - 2$

$5y + 4 = 3y + 6 \\ 5y - 3y = 6 - 4 \\ 2y = 2 \\ y = 1$

$5t + 3 = 2t + 15 \\ 5t - 2t = 15 - 3 \\ 3t = 12 \\ t = 4$

$6k + 5 = 2k + 1 \\ 4k = - 4 \\ k = - 1$

$8s - 1 = 6s - 5 \\ 2s = - 4 \\ s = - 2$

$5(x - 2) = 3(x + 4) \\ 5x - 10 = 3x + 12 \\ 2x = 22 \\ x = 11$

$3(h - 6) = 2(5 - 2h) \\ 3h - 18 = 10 - 4h \\ 7h = 28 \\ h = 4$

$2(5c + 2) - 2c = 3(2c + 3) + 7 \\ 10c + 4 - 2c = 6c + 9 + 7 \\ 8c - 6c = 16 - 4 \\ 2c = 12 \\ c = 6$
