Question

8. Rezolvati in Z ecuatiile:
a) 2(x + 1)-9 = x-5;
b) 366-2) + 6 = 4x + 3;
c) 7x + 3 = 5(x - 1) + 3;
d) 6-3(x-5) = 4x +7;
c) 2x - 70x+1) -3x+1;
1) 10-(4x-3) = -3(2x + 3);
88 - 5(x - 2) = 4 + 3(x + 2); h) 2x + 3(3-X) = 1 - (2-x);
02x-1)-3(x-2)=40x+1)-5(2-x);
D7x-4(2x + 3) = 2(4x-3)+3(2-x).​

Answer 1

Răspuns:
