Question

3 –2x + 4·[3 + 5·(x+1)] = 10x –7

Answer 1

Respuesta:

x = 5,25

Explicación paso a paso:

3 - 2x + 4.[ 3 + 5.(x + 1)] = 10x - 7

3 - 2x + 4. [ 3 + 5x + 5] = 10x - 7

3 - 2x + 4.[8 + 5x] = 10x - 7

3 - 2x + 32 + 20x = 10x - 7

-2x +20x -10x = -7 - 3 - 32

8x = 42

$x = \frac{42}{8}$

$x = \frac{21}{4}$

x = 5,25
