Respuesta:
1) 4x = 40 2) x + 5 = 10 3) x + 8 = 11
x = 40/4 x = 10 - 5 x = 11 - 8
x= 10 x = 5 x = 3
4) x - 11 = 16 5) x - 9 = 21 6) x + 3 = 32
x = 16 + 11 x = 21 + 9 x = 32 - 3
x = 27 x = 30 x = 29
7) 6x = 42 8) x + 14 = 46 9) 8x = 32
x = 42/6 x = 46 - 14 x = 32/8
x = 7 x = 32 x = 4
10) x + 4 = 64
x = 64 - 4
x = 60
