1)-х=42-30, х=-12; 2)-х=-1-62, х=63; 3)-х=-18-82, х=100; 4)-х=0+18, х=-18; 5)-х=10+10, х =-20
1) 30 - х = 42 4) 82 - х = = - 18 х = 30 - 42 х = 82 - (- 18) х = - 12 х = 100 2) х - 0 = -19 5) -18 - х = 0 х = - 19 х = -18 - 0 х = - 18 3) 62 - х = - 1 х = 62 -(- 1) 6) -10 - х = 10 х = 63 х = - 10 - 10 х = - 20
