Question

3×-8=2(×+10) algem me ajuda nessa também 5(×+10)=3(×-6)

Answer 1

$\mathtt{3x - 8 = 2~.~(x + 10)} \\ \mathtt{3x - 8 = 2x + 20} \\ \mathtt{3x - 2x = 20 + 8} \\ \mathtt{x = 28} \\ \\ \boxed{\mathtt{Resposta' = x = 28}} \\ \\ \\ \mathtt{5~.~(x + 10) = 3 ~.~(x - 6)} \\ \mathtt{5x + 50 = 3x - 18} \\ \mathtt{5x - 3x = - 18 - 50} \\ \mathtt{2x = -68} \\ \mathtt{x = - 68 \div2} \\ \mathtt{x = 34} \\ \\ \boxed{\mathtt{Resposta: x = 34}}$

Answer 2

$\mathtt{3x - 8 = 2~.~(x + 10)} \\ \mathtt{3x - 8 = 2x + 20} \\ \mathtt{3x - 2x = 20 + 8} \\ \mathtt{x = 28} \\ \\ \boxed{\mathtt{Resposta' = x = 28}} \\ \\ \\ \mathtt{5~.~(x + 10) = 3 ~.~(x - 6)} \\ \mathtt{5x + 50 = 3x - 18} \\ \mathtt{5x - 3x = - 18 - 50} \\ \mathtt{2x = -68} \\ \mathtt{x = - 68 \div2} \\ \mathtt{x = 34} \\ \\ \boxed{\mathtt{Resposta: x = 34}}$
