Question

Rezolvati ecuatiile! ​

Answer 1

a) x-4 = 0; x = 4

b) -2-x = 0; -x = 2; x = -2

c) 3x-4 = 0; 3x = 4; x = 4/3

d) 1-2x = 0; -2x = -1; x = 1/2

e) 3/2 - x/5 = 0; 15-2x = 0; -2x = -15; x = 15/2

f) V5x+1 = 0; V5x = -1; x = -1/V5; x = -V5/5

g) => -V3x = -V2-1; x = V2/V3 + 1/V3 ;

x = (V6+V3)/3
