Question

3. Rezolvati in Z ecuatiile următoare: a) 2x = -8: b) 3x = -6; e) - 4x = -12: f) -3x = -15; - c) 4x =-8; g) -2x = -14; d) 3x = -9; h) -4x=-24​

Answer 1

a) 2x = -8 ; x = -8:2 ; x = -4

b) 3x = -6 ; x = -6:3 ; x = -2

e) -4x = -12 ; x = -12 : -4 = 12 : 4 = 3 ; x = 3

f) -3x = -15 ; x = -15 : -3 = 15 : 3 = 5 ; x = 5

c) 4x = -8 ; x = -8 : 4 ; x = -2

g) -2x = -14 ; x = -14 : -2 = 14 : 7 ; x = 2

d) 3x = -9 ; x = -9 : 3 ; x = -3

h) -4x = -24 ; x = 24: 4 ; x = 6
