Question

raiz quadrada de 7x-1=raiz quadrada de 5x+1 (É equações irracionais)

Answer 1

$\sqrt{7x+1}= \sqrt{5x+1} ==\ \textgreater \ 7x+1= ( \sqrt{5x+1})^2===\ \textgreater \ 7x+1=5x+1$

7x-5x=1-1
2x=0
x=0

Answer 2

Olá, boa tarde ☺

Resolução:

√(7x-1)=√(5x-1)
√(7x-1)²=√(5x-1)²
7x-1=5x-1
7x - 5x = -1 + 1
2x= 0
x=0/2
x= 0

Bons estudos :)
