Question

2.(x+1)+x=32
x+2.(x+1)=206
me ajudem, por favor

Answer 1

2.(x+1)+x=32
2x+2+x=32
2x+x=32-2
3x=30
x=30/3
x=10

x+2.(x+1)=206
x + 2(1 + x) = 206
x + (1 * 2 + x * 2) = 206
x + (2 + 2x) = 206
2 + x + 2x = 206
x + 2x = 3x
2 + 3x = 206
2 + 3x = 206
2 + -2 + 3x = 206 + -2
2 + -2 = 0
0 + 3x = 206 + -2
3x = 206 + -2
206 + -2 = 204
3x = 204
x = 68
