me ajudem pfv

Answer 1

Resposta:

a) x= 8. f) x= 0.

b) x= -34. g) x= 199.

c) x= 8. h) x= 516.

d) x= 10. i) x= -4.

e) x= -2. j) x= 772.

Explicação passo-a-passo:

a) x+5= 13

x= 13-5

x= 8

b) x+18= -13

x= -13-18

x= -34

c) x+1= 9

x= 9-1

x= 8

d) x-2= 8

x= 8+2

x= 10

e) x-8= -10

x= -10+8

x= -2

f) x+3= 3

x= 3-3

x= 0

g) x+101= 300

x= 300-101

x= 199

h) x-279= 237

x= 237+279

x= 516

i) 17+x= 13

x= 13-17

x= -4

j) 128+x= 900

x= 900-128

x= 772
