Answer 1

Explicație pas cu pas:

h)

376 - (25 + 106 - x) = 319

376 - 25 - 106 + x = 319

245 + x = 319

x = 319 - 245

=> x = 74

i)

37x = 222

x = 222 : 37

=> x = 6

j)

13x = 2613

x = 2613 : 13

=> x = 201

k)

207 : x = 23

x = 207 : 23

=> x = 9

l)

x : 17 = 6

x = 17•6

=> x = 102

m)

3•(2x - 1) - 1 = 32

3•(2x - 1) = 32 + 1

3•(2x - 1) = 33 | (:3)

2x - 1 = 11

2x = 11 + 1

2x = 12

x = 12 : 2

=> x = 6
