Question

Me ajudem: Resolva as equações de primeiro grau:
a) -2x = -10
b)6x = 2x + 16

Answer 1

a)
$(-2)x=-10 \\ \\ (-2)x=-10*(-1) \\ \\ 2x=10 \\ \\ x= \frac{10}{2} \\ \\ x=5$

b)
$6x=2x+16 \\ \\ 6x-2x=16 \\ \\ 4x=16 \\ \\ x= \frac{16}{4} \\ \\ x=4$

Answer 2

$a) - 2x = - 10$

$x = \frac{10}{2}$

$x = 5$

______________________________________

$b)6x = 2x + 16$

$6x - 2x = 16$

$4x = 16$

$x = \frac{16}{4}$

$x = 4$
