Question

Resolva as seguintes equa¸c˜oes:

(a) x+4 =9

(b) 10 = y−6

(c) y +15 = 6

(d) x+6 =−10

(e) x−2 =−3

Mandem os c´alculos junto com as repostas.

me ajudem plase!​

Answer 1

a) x+4=9 :   x = 5

b) 10=y-6   : y = 16

c) y+15=6  :  y = -9

d) x+6=-10  :   x = -16

e) x-2=-3   :   x = -1

Answer 2

( a ) x + 4 = 9 =

x = 9 – 4 =

x = 5

( b ) 10 = y – 6 =

10 – y = – 6 =

– y = – 6 – 10 =

– y = – 16 =

y = 16

( c ) y + 15 = 6 =

y = 6 – 15 =

y = – 9

( d ) x + 6 = – 10 =

x = – 10 – 6 =

x = – 16

( e ) x – 2 = – 3 =

x = – 3 + 2 =

x = – 1
