Question

(70-70:m):4+3=20 AJUTOR!!

Answer 1

(70-70:m):4+3=20

(70-70:m):4 = 20 - 3

(70 - 70 : m) : 4 = 17

70 - 70 : m = 17 × 4

70 - 70 : m = 68

70 : m = 70 - 68

70 : m = 2

m = 70 : 2

m = 35

Answer 2

==> ( 70 - 70 : m ) : 4 + 3 = 20
==> ( 70 - a ) : 4 + 3 = 20
==> b : 4 + 3 = 20
==> b : 4 = 20 - 3 
==> b : 4 = 17
==> b = 17 x 4
==> b = 68
==> 70 - a = b
==> 70 - a = 68
==> a = 70 - 68
==> a = 2
==> 70 : m = a
==> 70 : m = 2
==> m = 70 : 2
==> m = 35
