Question

gente me ajuda a resolve r por favor...

Answer 1

3x - 3 + x - 1 = 2x - 3
 12          8         6

mmc de 12, 8 e 6 = 24

2(3x - 3) + 3(x - 1) = 4 (2x - 3)
            24                     24

2(3x - 3) + 3 (x - 1) = 4(2x - 3)
6x - 6 + 3x - 3 = 8x - 12
9x - 9 = 8x - 12
9x - 8x = - 12 + 9
x = - 3
