Answer 1

1)x+45=18

x=18-45

x=-27

2)-63-x=-11

-x=-11+63

x=-52

3)27+x=5

x=5-27

x=-22

4)-99+x=-6

x=-6+99

x=93

5)-x+7=-2

-x=-2-7

x=9

6)2-x=-5

-x=-5-2

x=7

7)x+3,12=-5,43

x=-5,43-3,12

x=-8,55

8)$1\frac{3}{14} -y=2\frac{7}{10}\\-y=\frac{27}{10}-\frac{17}{14}\\y=-1\frac{17}{35}$

9)5,23+y=-7,24

y=-7,24-5,23

y=-12,47

10)$y-2\frac{5}{12}=-3\frac{7}{15} \\y=-3\frac{7}{15}+2\frac{5}{12}\\y=-1\frac{1}{20}$
