Question

Escribe como resolviste las siguientes ecuaciones. ​

Answer 1

Explicación paso a paso:

2x + 3x + 5 = 65 -6x+ 8 = 2x + 64

2x + 3x = 65 - 5 -6x -2x = 64 - 8

5x = 60 -8x = 56

x = 60 x = -56/8

x = 12 x = -7

15 - a + 4a = -6 m + 14 - 2m = - 8

4a - a = -6 - 15 m - 2m = - 8 - 14

3a = - 21 - m = - 22

a = -21/3 m = 22

a = - 7

4x + 6 = - x - 14 - 6x + 8 = 2x + 64

4x + x = - 14 - 6 -6 x - 2 x =64 - 8

5x = - 20 -8 x = 56

x = - 20/5 x = - 56

x = - 4

3 y + 6 = - 30 + 2y 2(6 + 5×) -11 = 71

3y - 2y = -30 - 6 12 + 10x - 11 = 71

y = - 36 10x = 71 + 11 -12

10x = 70

x = 70/10

x = 7

4( 8 - 4n ) = 2( n - 40 ) + 4 6(2x + 5) = - 3(-x + 2)

32 - 16n = 2n - 80 + 4 12x + 30 = 3x - 6

-16n - 2n = -80 +4 +32 12x -3x = -30 - 6

-18n = -56 9x = - 36

n = -56/-18 x = -36/9

n = 3 x = - 4
