Answer 1

Respuesta:

a) y = -6

b) x = 7

c) x = 5

Explicación paso a paso:

a) 3(y+4) +6 = 5(y+6)

=> 3y +12 +6 = 5y + 30

=> 18 - 30 = 5y - 3y

=> -12 = 2y

=> -6 = y

b) 9x-10 = 4x+25

=>9x - 4x = 25+10

=> 5x = 35

=> x = 7

c) 15x - 5(2x-1) = 3(3x-5)

=> 15x -10x +5 = 9x -15

=> 15 +5 = 9x - 5x

=> 20 = 4x

=> 5 = x
