Question

3x= x-3/4 + 2, qual valor de x?

Answer 1

$3x = x - (3/4)+2 \\ 4*3x=4*x-4*(3/4)+4*2 \\ 12x=4x-3+8 \\ 12x-4x=5 \\ 8x=5 \\ x=5/8$

$3x=[(x-3)/4] + 2 \\ 4*3x=4*[(x-3)/4]+4*2 \\ 12x=x-3+8 \\ 12x-x=5 \\ 11x=5 \\ x=5/11$

Answer 2

3x=x-3/4 +2               mmc 4,1 = 4
12x/4=x-3/4+8/4
12x=x-3+8
12x-x=-3+8
11x=5
x=5/11
