1. -85+12×=35
12×=35+85
12×=120
×=120:12
×=10

2.8x+52=60
8×=60+52
8x=112
×=112:8
×=14

3.10x+9=31
10x=31+9
10x=40
×=40:10
×=4

4. -59+15x=11
15x=11+59
15x=70
x=14/3

5.12y=69-y
12y+y=69
13y=69
y=69/13

6. 13y-80=7y
13y-7y=80
6y=80
y=40/3

7. 4 (x-6)=224
x-6=54
x=54+6
×=60

8. -5+2x=-3+x
2x-x=-3+5
x=-3+5
×=2

Succes. Mi-a luat mult
