Question

7(x-5) =3(x+1)
$7(x - 5 ) = 3(x + 1)$
​

Answer 1

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

7x-35=3x+3

7x-3x=3+35

4x=38

x=9,50

Answer 2

Resposta:

$x = \frac{19}{2}$

Explicação passo-a-passo:

$7(x - 5) = 3(x + 1) \\ 7x - 35 = 3x + 3 \\ 7x - 3x = 3 + 35 \\ 4x = 38 \\ x = \frac{38 \div2 }{4 \div 2} \\ \\ \bf{x = \frac{19}{2} }$
