Решите уравнение: x*6-2=124, (t+5)*4=100, a/8*10=160, (z-10) /2=55

x * 6 - 2 = 124
6х = 124 + 2
6х = 126
х = 21

(t + 5) * 4 = 100
4t + 20 = 100
4t = 100 - 20
4t = 80
t = 20

a / 8 * 10 = 160
а / 8 = 160 : 10
а / 8 = 16
а = 16 * 8
а = 128

(z - 10) / 2 = 55
z - 10 = 55 * 2 
z - 10 = 110
z = 110 + 10
z = 120
