3. 2x=19-5
4. x-8=12
5. 5x=20
6. 3x=29
7. x-21=86
8. (x+2)-1=7
9. 6m-8=26
10. -4i-13=7
11. 12u +18= - 30


Voy en 7 grado lo necesito urgente ayudenme

Answer 1

Respuesta:

$1.x = 4 \\ 2.x = 20 \\ 3.x = 7 \\ 4.x = 20 \\ 5.x = 4 \\ 6.x = \frac{29}{3}$

$1.x = 4 \\ 2.x = 20 \\ 3.x = 7 \\ 4.x = 20 \\ 5.x = 4 \\ 6.x = \frac{29}{3}$$7.x = 107 \\ 8.x = 6 \\ 9.m = \frac{34}{6} = \frac{17}{3} \\ 10.4i + 13 = - 7 - > i = \frac{ - 20}{4} \\ i = - 5$

$11.u = \frac{ - 48}{12} = - 4$
