ajutati-ma va rog mult ....rezolvați acest exercitiu

Answer 1

a) x-2/3<1/3, x<1/3+2/3, x<1
b)x+7/5>2/5, x>2/5-7/5, x>-1
c) x-3/7$\leq$4/7, x$\leq$3/7+4/7, x$\leq$1
d)1/4-x$\geq$9/4, -x$\geq$9/4-1/4, -x$\geq$9/4-1/4
-x$\geq \geq$2, inmultim cu -1(se schimba si sensul inegalitatii)x$\leq$-2
e) 9/2-x<1/2, -x<1/2-9/2, -x<-4, *-1, x>4
f) 3/8-x$\leq$11/8, -x$\leq$11/8-3/8, -x$\leq$1 *-1 si avem x$\geq$-1
