Răspuns :
1) 5x + 20 - ( 50 - 48 ) x = 41
5x + 20 - 2x = 41
5x - 2x = 41 - 20
3x = 21
x = 21 : 3
x = 7
2) 308x - ( 6x - 2x ) × 2 = 300
308x - 4x × 2 = 300
308x - 8x = 300
300x = 300
x = 300 : 300
x = 1

Explicație pas cu pas:
1) 5x + 20 - ( 50 - 48 ) x = 41
5x + 20 - 2x = 41
5x - 2x = 41 - 20
3x = 21
x = 21 : 3
x = 7
2) 308x - ( 6x - 2x ) × 2 = 300
308x - 4x × 2 = 300
308x - 8x = 300
300x = 300
x = 300 : 300
x = 1
