Question

ME AJUDEM POR FAVOR
e) 14 = -4(y-3) - 3

f) z- (2z - 4) + 19 = 8

g) 2 + 3 (x - 4) - (2x - 7) = 137

h) 5/4x + 0,5 = 2

i) 3/4x - 10 = x/2

j)15-2/3x - 1 = 14,2

k)2/3x - 0,7 = - x + 5,3

Answer 1

E) 14 = -4y +12-3 ; 14 = -4y +9; -4y = 5 ; y = (-5/4)
F) z-2z+4+19=8; -z = -15; z=15
G) 2 + 3x -12 -2x +7 =137 ; x = 140
H) (5/4)x + (5/10) = 2 ; (5/4)x = (20-5) / 10;  (5/4)x = 15/10; x = 60/50 = 1,2
I) (3/4)x - (x/2) = 10; (3x -2x)/4 = 10 ; x = 40
J) (-2/3)x = 2/10 ; x= -6/20
K) (2/3)x +x = 6; (2x +3x)/3 = 6; 5x = 18 ; x = 18/5;

Cumprimentos, Ruuki.
