a) 2y - 5 = y + 1
c) 3 (2x + 3) - 3= 4(x - 1)
e) 2 (x - 1) = x + 2 me ajude mostre o desinvolvimento​

Answer 1

a) 2y - 5 = y + 1

2y - y = 1 + 5

y = 6

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

6x + 9 - 3 = 4x - 4

6x - 4x = -4 - 6

2x = -10

x= -10/2

x= -5

e) 2 (x - 1) = x + 2

2x - 2 = x + 2

2x - x = 2 + 2

x = 4
