Question

Determine o zero da função 1 grau y=2x-12

Answer 1

$x,f(x)=2x-12~~~~(~iguale~a~zero)\\\\\\2x-12=0~~~~(some~12~em~ambos~os~lados~da~igualdade)\\\\\\2x-12\hspace{-9}\diagup+12\hspace{-9}\diagup=0+12\\\\\\2x=12~~~~(divida ~ambos~os~lados~da~igualdade~por~2)\\\\\\ \dfrac{2\hspace{-7}\diagup x}{2\hspace{-7}\diagup}=\dfrac{12}{2}\\\\\\ \large\boxed{\boxed{x= 6}}$

Answer 2

2x-12=0
2x=12
x = 12/2
x = 6
O valor de X, ou seja, o zero da função é 6
