Ok mira haci es como se resuelven, y lo se pq estoy en 2do grado de secundaria.
●Procedimiento paso a paso con las ecuaciones :
1) 10x - 10 = 5 ( x + 2 )
10x - 10 = 5x + 10
10x - 5x = 10 + 10
5x = 20
x = 20 / 5
x = 4.
R : 4.
2) 4 ( x + 5 ) = 2x + 34
4x + 20 = 2x + 34
4x - 2x = 34 - 20
2x = 14
x = 14 / 2
x = 7.
R : 7.
3) 10 ( x + 2 ) = 8x + 22
10x + 20 = 8x + 22
10x - 8x = 22 - 20
2x = 2
x = 2 / 2
x = 1.
R : 1.
4) 5 ( x + 4 ) = 3 ( x + 10 ) - 8
5x + 20 = 3x + 30 - 8
5x - 3x = 30 - 8 - 20
2x = 2
x = 2 / 2
x = 1.
R : 1.
5) x + 19 = 2 ( x + 6 )
x + 19 = 2x + 12
x - 2x = 12 - 19 - 1x = - 7
x = - 7 / - 1
x = 7.
R : 7.
6) 4 ( x + 10 ) = 2 ( x + 22 )
4x + 40 = 2x + 44
4x - 2x = 44 - 40
2x = 4
x = 4 / 2
x = 2.
R : 2.
7) 6 ( x + 5 ) = 7x + 25
6x + 30 = 7x + 25
6x - 7x = 25 - 30 - 1x = - 5
x = - 5 / - 1
x = 5.
R : 5.
8) 7 ( x + 4 ) = 5 ( x + 6 ) + 6
7x + 28 = 5x + 30 + 6
7x - 5x = 30 + 6 - 28
2x = 8
x = 8 / 2
x = 4.
R : 4.
9) 4 ( x + 2 ) = 20 ( x - 6 )
4x + 8 = 20x - 120
4x - 20x = - 120 - 8 - 16x = - 128
x = - 128 / - 16
x = 8.
R : 8.
10) 5 ( x + 5 ) = 2x + 40
5x + 25 = 2x + 40
5x - 2x = 40 - 25
3x = 15
x = 15 / 3
x = 5.
R : 5.
Espero haberte ayudado muchísimo tq❤.
