1) 37,6x - (10 - 41,2x) + 7,13 = 37,6x - 10 + 41,2x + 7,13= 37,6x + 41,2x - 10 + 7,13= 78,8x - 2,87
2) 8,8 + 13,19y - (15,1y + 20,02) = 8,8 + 13,19y - 15,1y - 20,02= 13,19y - 15,1y + 8,8 - 20,02= -1,91y - 11,22
1) 37,6x - (10 - 41,2x) + 7,13 = 37,6x - 10 + 41,2x + 7,13
= 37,6x + 41,2x - 10 + 7,13
= 78,8x - 2,87
2) 8,8 + 13,19y - (15,1y + 20,02) = 8,8 + 13,19y - 15,1y - 20,02
= 13,19y - 15,1y + 8,8 - 20,02
= -1,91y - 11,22
