Question

7(x-1) =3x+1

(x+2).6=2(10+x)

(35x-50):5=2x+15

doy todos mis puntos, corazón,todo ​

Answer 1

7( x - 1) = 3x + 1

7x - 7 = 3x + 1

7x - 3x = 1 + 7

4x = 8

x = 2

( x + 2 ) . 6 = 2 ( 10+ x )

6x + 12 = 20 + 2x

6x - 2x = 20 - 12

4x = 8

x = 2

(35x - 50) 5 = 2x + 15

175x - 250 = 2x + 15

175x - 2x = 15 + 250

173x = 265

x = 265 / 173 = 1, 53179
