$1)2(x + 5) = 16 \\ 2x + 10 = 16 \\ 2x = 16 - 10 \\ 2x = 6 \\ x = 3$

$2)3(t + 1) = 18 \\ 3t + 3 = 18 \\ 3t = 18 - 3 \\ 3t = 15 \\ t = 5$

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

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

$5)2(3x + 1) = 11 \\ 6x + 2 = 11 \\ 6x = 11 - 2 \\ 6x = 9 \\ x = \frac{9}{6} \\ x = \frac{3}{2}$

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

$7)9(3x - 5) = 9 \\ 27x - 45 = 9 \\ 27x = 9 + 45 \\ 27x = 54 \\ x = 2$

$8)3(t + 7) = 15 \\ 3t + 21 = 15 \\ 3t = 15 - 21 \\ 3t = - 6 \\ t = - 2$

$9)5y + 4 = 3y + 6 \\ 5y - 3y = 6 - 4 \\ 2y = 2 \\ y = 1$

$10)5t + 3 = 2t + 15 \\ 5t - 2t = 15 - 3 \\ 3t = 12 \\ t = 4$

$11)6k + 5 = 2k + 1 \\ 6k - 2k = 1 - 5 \\ 4k = - 4 \\ k = - 1$

$12)8s - 1 = 6s - 5 \\ 8s - 6s = - 5 + 1 \\ 2s = - 4 \\ s = - 2$

$13)5(x - 2) = 3(x + 4) \\ 5x - 10 = 3x + 12 \\ 5x - 3x = 12 + 10 \\ 2x = 22 \\ x = 11$

$14)3(h - 6) = 2(5 - 2h) \\ 3h - 18 = 10 - 4h \\ 3h + 4h = 10 + 18 \\ 7h = 28 \\ h = 4$

$15)2(5c + 2) - 2c = 3(2c + 3) + 7 \\ 10c + 4 - 2c = 6c + 9 + 7 \\ 8c + 4 = 6c + 16 \\ 8c - 6c = 16 - 4 \\ 2c = 12 \\ c = 6$

$4x - 7 = 1 + 2x \\ 4x - 2x = 1 + 7 \\ 2x = 8 \\ x = 4$

$2m + 310 = 806 \\ 2m = 806 - 310 \\ 2m = 496 \\ m = 248$

$3x - 102 = 285 \\ 3x = 285 + 102 \\ 3x = 387 \\ x = 129$

$3y + 47 = 83 - y \\ 3y + y = 83 - 47 \\ 4y = 36 \\ y = 9$

$5x - 19 = 2x + 65 \\ 5x - 2x = 65 + 19 \\ 3x = 84 \\ x = 28$

$8m + 14 = m + 56 \\ 8m - m = 56 - 14 \\ 7m = 42 \\ m = 6$

$2y + 60 - 18 = 340 \\ 2y + 42 = 340 \\ 2y = 340 - 42 \\ 2y = 298 \\ y = 149$
