Question

rezolvatii ecuatiile x-2 28=-x-18
 x+2=5 ori (24-x-2 )  

Answer 1

x - 2 + 28 = - x - 18
x + x = -18 + 2 - 28
2x = - 16 - 28
2x = - 44
x = - 22

x + 2 = 5 * (24 - x -2) 
x + 2 = 120 - 5x - 10
x + 5x = 120 - 10 - 2
6x = 110 - 2
6x = 108
x = 18

Answer 2

$x-2+28=-x-18 \\ x+x=-18-28+2 \\ 2x=-44 \\ x=-44:2 \\ x=-22 \\ \\ x+2=5(24-x-2) \\ x+2=120-5x-10 \\ x+5x=120-10-2 \\ 6x=108 \\ x=108:6 \\ x=18$
