me ajudemmmmm plmdss ❤.

Answer 1

a) x - 3 = 7

x = 7 + 3

x = 10

b) x + 4 = 10

x = 10 - 4

x = 6

c) x + 101 = 300

x = 300 - 101

x = 199

d) x - 279 = 237

x = 237 + 279

x = 516

e) x - 8 = - 10

x = - 10 + 8

x = - 2

f) x + 9 = - 1

x = - 1 - 9

x = - 10

g) 3x = 12

x = 12

---

3

x = 4

h) 9x = 18

x = 18

---

9

x = 2

i) 35x = 18

x = 18

----

35

x = 0,51

j) 7x - 1 = 13

7x = 13 + 1

7x = 14

x = 14

---

7

x = 2

Answer 2

A) X-3=7

X=7+3

X=10

B)x+4=10

x=10-4

X=6

C) X+101=300

X=300-101

X=199

D) X-279=237

X=237+279

X=516

E) X-8=-10

X=-2

F)x+9=-1

x=-9-1

X=-10

G) 3x=12

x=4

h) 9x=18

x=2

I) 35x=18

x=18/35

J) 7x-1=13

7x=13+1

7x=14

x=2

É isso espero ter ajudado (ùwú )z♡
