Equação de 1° grau
Exemplo:
5x+7=2x+4
Regra Básica: Números c/ letra ou só letras antes do = e números sem,vão do outro lado
No exemplo acima irá ficar: 5x-2x,como o 2x estava depois do igual positivo (+2x) ele passou a ser -2x
por isso -2x
o 7 está positivo e antes do igual, então ele vai para o outro lado como -7
Então ficará: 5x-2x=4-7
Agora é só resolver:
5x-2x= 3x
4-7= -3
3x= -3
Agora vamos dividir : 3/-3
x= 3/3
x=-1
