Question

Rezolvati ecuatiile urmatoare in Q. A)4x+7=x-3 B). 3(2x+1)=5x-2. C) 2(x-4)-7=3(1-x)-15

Answer 1

A . 4x-1x = -7-3
3x=-10
x= -10 supra 3

B . 6x + 3 = 5x-2
6x-5x=-3-2
x=-5

C . 2x-8 -7=3-3x-15
 2x+3x= +8+7+3-15
5x= 3
x= 3 supra 5 :*

Answer 2

A)4x-x=-3-7
3x=10
x=10:3 =3.(3)\

B) 6x + 3 =5x-2
6x-5x=-2-3
+1x=-5
x=-5:1=5 

C) ?
