|x + 3| - 1 = 5
|x + 3| = 6
1) x + 3 = -6, X1 = -9
2) x + 3 = 6, X2 = 3
(-9 + 3) / 2 = -3 средне арифметическое корней.
-6:8+2,34-3445-6756-776 = - 10 975,41
1) -6:8 = - 3/4 = -0,75
2) -0,75+2,34 = 1,59
3) 1,59-3445 = -3443,41
4) -3443,41-6756 = -10199,41
5) -10199,41-776 = -10975,41
1) 38-23=15
2) 5×9=45
