10 mais x menos 2 igual 5 menos x mais 4

Answer 1

$\mathtt{10+x-2=5-x+4} \\ \mathtt{x + 10 - 2 = - x + 5 + 4 } \\ \mathtt{x+8=-x+9} \\ \mathtt{x + x = 9 - 8} \\ \mathtt{2x = 1} \\ \black{\mathtt{x = \frac{1}{2}}} \\ \\ \\ \boxed{\boxed{\mathtt{Resposta: \dfrac{1}{2}}}}$

Answer 2

10+x-2=5-x+4

x+x=2+5+4-10

2x=11-10

2x=1

x=1/2
