Respuesta:
1) n = 19
2) x = 60
Explicación paso a paso:
1) 4n - 1 = 5 × 15
4n = 75 + 1
4n = 76
n = 76 ÷ 4 = 19
--------------------------------------------------
2) x/5 - 1 = 22/2
x/5 = 11 + 1 = 12
x = 12 × 5 = 60
1). 4x - 11 = 5(15)
4x - 11 = 75
4x = 75 + 11
4x = 86
x = 86 / 4
x = 21.5
2). (x/5) - 1 = 22 / 2
(x/5) - 1 = 11
(x/5) = 11 + 1
(x/5) = 12
x = 12 * 5
x = 60
