4X +2 = 22
3X = 12
2X -34 = 120
10X + 5 = 3X +12
X-15 = -27
- 11X + 12 = 144
5X -2= 13
2X +3 = -3X-2​

Answer 1

Respuesta:

4X +2 = 22  => x = 5

3X = 12   => x = 4

2X -34 = 120   => x = 77

10X + 5 = 3X +12   => x = 1

X-15 = -27   => x = -12

- 11X + 12 = 144   => x = -12

5X -2= 13   => x = 3

2X +3 = -3X-2​  => x = -1
