Question

HALLA EL VALOR DE X

1) 2(x-5) = 3x-17
2) 2(2+4x) = 3 + 12x
3) 5x = 7(5x - 3 ) + 3

Answer 1

Explicación paso a paso:

1) 2(x-5) = 3x-17

2x - 10 = 3x -17

-10+17 = 3x-2x

7 = x

2) 2(2+4x) = 3 + 12x

4 + 8x = 3 +12x

4 -3 = 12x -8x

1 = 4x

1/4 = x

3) 5x = 7(5x - 3 ) + 3

5x = 35x - 21 + 3

5x = 35x - 18

18 = 35x - 5x

18 = 30x

18/30 = x

3/5 = x
