Question

Resuelve las siguientes ecuaciones:
2(2x – 3) = 6 + x
2x – 3 = 6 + x
3/4(2y + 4) = y +19
4 (x-10)= -6(2-x)-6x

Answer 1

2(2x – 3) = 6 + x

4x-6=6+x

4x-x=6+6

 3x=12

 x=12/3

 x=4

2x – 3 = 6 + x

2x-x=6+3

 x=9

4 (x-10)= -6(2-x)-6x

4x-40=-12+6x-6x

4x-6x+6x=-12+40

 4x=28

 x=28/4

 x=7
