Question

Rezolvati ecuatiile:

a) -10= x:0,6

b) 2x + 4 supra 11=0

c) 3 supra 5x-3 supra 10=0

d) 8x-1=0 Va rogg repede am nevoie urgent e o situatie mai dificila dau coroana fac orice!

Answer 1

a) -10=x : 0,6;
x : 6/10=-10;
x : 3/5=-10;
x=-10•3/5=-30/5=-6;

b) 2x+4/11=0;
22x+4=0;
22x=-4;
x=-4/22;
x=-2/11;

c) 3/5x-3/10=0;
3/5x=3/10;
3•10=5x•3;
30=15x;
x=30/15;
x=2;

d) 8x-1=0;
8x=1;
x=1/8;
