Answer:

x = 3

Step-by-step explanation:

3 ( x + 1 ) = 5 ( x- 2 ) + 7

Expand

3 x + 3 = 5 x - 10 + 7

Minus 5 x from both sides

- 2 x + 3 = - 10 + 7

Minus 3 from both sides

- 2 x = - 10 + 4

Simplify

- 2 x = - 6

Divide both sides by - 2

x = 3

$\frac{8*( \frac{c}{c} )- \frac{3}{c} }{2*( \frac{7c}{7c})+ \frac{3}{7c} } \\ \\ \frac{ \frac{8c-3}{c} }{ \frac{14c+3}{7c} } \\ \\ \frac{8c-3}{c} * \frac{7c}{14c+3} \\ \\ = \frac{56c-21}{14c+3}$
