Question

A) 2X+4=10
B) 5X-15=20
C) 2X+15X=22
D) 2X+2=24

Answer 1

a) 2x + 4 = 10
2x = 10 - 4
2x = 6
x = 6 ÷ 2
x = 3

b) 5x - 15 = 20
5x = 20 + 15
5x = 35
x = 35 ÷ 5
x = 7

c) 2x + 15x = 22
17x = 22
x = 22 ÷ 17
x = 1,29...

d) 2x + 2 = 24
2x = 24 - 2
2x = 22
x = 22 ÷ 2
x = 11

Bons estudos !!!

Answer 2

A) 2x+4=10. B) 5x-15=20. C) 2x+15x=22. D) 2x+2=24
2x+4=10-4 5x-15=20+15. 2x+15x=22-15. 2x+2=24 - 2
X=10. X=20. X=22. X=24
X=6. X=35. . X=7. X=22
