Question

a) 12x+4-9x=14x+8
b) 8x-6= -24x + 10
c) 8(4y + 10)=6(10y-4)
d) X+2=2
e) 18x+18x-2-5x+4= 2​

Answer 1

Explicación paso a paso:

a) 12x + 4 -9x = 14x + 8

12x -9x - 14x = 8 - 4

- 11x = 4

x = 4/11

b) 8x - 6 = -24x + 10

8x + 24x / 10 + 6

32x = 16

x = 16/32

c) 8(4y + 10) = 6(10y - 4)

32y + 80 = 60y - 24

80 +24 = 60y + 32y

104 = 92y

1,01 = y
