Question

2.X+10+X=4.3 Porfavor!!!!!!!!! Lo recontra necesito. Porfi porfi

Answer 1

2.(x)+10+x=4.3
2x+10+x=12
2x+x=12-10
3x=2
x=2/3

Answer 2

2x + 10 +x = 4 .3
2x + 10 +x= 12
2x+ x = 12 - 10
2x + x = 2
3x = 2
x = 2 : 3
x = 0,666...

Comprobamos
2x + 10 + x = 4.3
2 . 0,666 + 10 + 0,666 = 12
1,332 + 10 + 0,666 = 12
11,332 + 0,666 = 12
11,998 = 12
12 = 12  (Redondeamos 11,998)
