Question

Sacar la incógnita de los siguientes valores ​

Answer 1

9)

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

10)

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

11)

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

12)

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

13)

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

14)

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

15)

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