Question

O valor de x na equação 2x – 4 = x + 8 é: *
​

Answer 1

$\boxed{\begin{array}{l}\sf 2x-4=x+8 \ ??\end{array}}$

então;

$\boxed{\begin{array}{lr}\Box \ 2x-4=x+8\\\Box \ 2x-x=8+4\\\Box \ x=8+4\\\Box \ \huge\boxed{\sf x=12 }\end{array}}$

O valor de X nessa equação é;

x=12

prova real;

$\boxed{\begin{array}{lr}2x-4=x+8\\24-4=12+8\\20=12+8\\20=20\\20-20=\\\huge\boxed{\sf R=0 \ \checkmark }\end{array}}$
