Question

A)5(x-2)=7(x-3)+3
resolva as equações​

Answer 1

$\mathsf{5(x-2)=7(x-3)+3}\\\mathsf{5x-10=7x-21+3}$

$\mathsf{7x-5x=21-3-10}\\\mathsf{2x=8}$

$\mathsf{x=\dfrac{8}{2}}$

$\boxed{\boxed{\bf{\mathsf{x=4}}}}$

Answer 2

Resposta:

Explicação passo-a-passo:

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

5x - 10 = 7x - 21 + 3

5x - 7x = -21 + 3 + 10

-2x = -8

-2x = -8 (-1)

2x = 8

x= 8 / 2

x= 4
