Question

Hallar La X
paso a paso

1) 2.(3X+1)=11

2) 6.(3X+5)=39

3) 5X+4=3X+6


​

Answer 1

Solución:

1)

$2(3x + 1) = 11 \\ 6x + 2 = 11 \\ 6x = 11 - 2 \\ 6x = 9 \\ x = \frac{9}{6} \\ x = 1.5$

2)

$6(3x + 5) = 39 \\ 18x + 30 = 39 \\ 18x = 39 - 30 \\ 18x = 9 \\ x = \frac{9}{18} \\ x = 0.5$

3)

$5x + 4 = 3x + 6 \\ 5x - 3x = 6 - 4 \\ 2x = 2 \\ x = \frac{2}{2} \\ x = 1$
