y + 465 = 1280
X-7 = 18
X-21 = 36
x-17 = 20
X-3.6 = 8.1
y-42 = 7.5
y-3.5 = 9.2
X
-
x-17 = 6
y-100 = 1910
X-75.9 = 12.8
x-13.4 = 4.9 +2.3​

Answer 1

Respuesta:

1-

x+5=8

x=8-5

x=3

2-

x+15=27

x=27-15

x= 12

3-

y+9=43

y=43-9

y=34

4-

5+x=7

x=7-5

x=2

5-

x+32=69

x=69-32

x=37

6-

y+74=183

y=183-74

y=109
