Question

Va rog dati mie citeva ecuatii pentru clasa 6 va rog mult rezolvate

Answer 1

4x+2=x+5
4x-x=5-2
3x=3
x=1

5x+12=27
5x=27-12
5x=15
x=3

4x+8= 12
4x=4 
x=1

3x+7=19
 3x=12
 x=4


2x+4-3(3x+4)=2-5(x-2)
 2x+4-9x-12=2-5x+10
 2x-9x+5x=2+10-4+12
-2x=20
 x=-10

Answer 2

3x+86=260
3x=260-86
3x=174
x=174:3
x=58
V: 3*58+86=260

17+(-2x)=11
-2x=11-17
-2x=-6
x=-6:(-2)
x=3
V: 17+(-2*3)=11

-10x+4=-96
-10x=-96-4
-10x=-100
x=-100:(-10)
x=10
V: -10*10+4=-96
