sendo U=Q,resolva
a)2x-6-2= -3x+2-3

b) y-6=5y+8-7y

c)6x-60=5x+76

d) 18y+3= -34y-4

Answer 1

Vamos lá

a) 2x-6-2= -3x+2-3

2x - 8 = -3x - 1

5x = 7

x = 7/5

b) y-6=5y+8-7y

y - 6 = -2y + 8

3y = 14

y = 14/3

c) 6x - 60 = 5x + 76

6x - 5x = 76 + 60

x = 136

d) 18y+3= -34y-4

18y + 34y = -4 - 3

52y = -7

y = -7/52
