Question

URGENTE
resolva e mostre passo a passo:
a)
10 (4x+14) - 2 = 8 (x-10) + 18

b)
y/10 + y/14 = 24
​

Answer 1

a) -25/4

b) 140

a)

10 (4x+14) - 2 = 8 (x-10) + 18

40x+140-2 = 8x-80+18

40x-8x = -80+18-140+2

32x = -200

x = -200/32

x = -25/4

b)

y/10 + y/14 = 24, MMC = 70

7y+5y = 1680

12y = 1680

y = 140

Cálculos

MMC 10,14 = 70

10-14|2

5-7|5

1-7|7 = 70
