Question

Rezolvati ecuatiile:
a)(2/9+x)*3=5intreg si 2/3
b)(3intreg si 1/2*x-1/4)*8=3
c)(x-4intreg si 1/3):1 intreg si 1/3=1 intreg si 2/5
d)(9-2 intreg si 2/15 *x)*9/14=1 intreg si 1/2
e)(7 intreg si 1/4)*7,2+2,8=9
f)(21-x)*6,6+3:0,6=22,82

Answer 1

a) 3(2/9 + x)=17/3
2/9+x=17/9
x=15/9 = 5/3

b) (7/2)x-1/4=3/8
(7/2)x=1/8
x=1/32

NU se intelege c, d)

e)29/4 * 72/10 +28/10 = 9          
29*18/10 +24/10= 9 (E gresit exercitiul)

f)(21-x) *66/10 + 3 * 10/6 = 2282/100 si faci calculele
