Question

equação 1 grau.

20-80+2×=16

E

19+2×-13=10-20

Answer 1

20 - 80 + 2x = 16

- 60 + 2x = 16

2x = 16 + 60

2x = 76

x = 76/2

x = 38
___________________________________________
19 + 2x - 13 = 10 - 20

2x + 6 = - 10

2x = - 10 - 6

2x = - 16

x = - 16/2

x = - 8


Forte abraço!

Answer 2

20-80+2x=16
-60+2x=16
2x=16+60
2x=76
x=76/2
x=38

19+2x-13=10-20
2x=-10-19+13
2x=-29+13
2x=-16
x=-16/2
x=-8
