Question

Identifique, a seguir, as sentenças que representam equações.

Answer 1

Resposta:

$8x + 3 = 3x +10 = x=\frac{7}{5}\\\\15 < 12 +18 = 30\\\\5^2+13= 38= 25\\\\x+3= 17= x = 14\\\\3x^2 \neq 16= x\ne \frac{4\sqrt{3}}{3} \mathrm{}\quad \:x\ne \:-\frac{4\sqrt{3}}{3}\\\\x+y+6= 20= x =7\ y= 7\\\\8= 3+3x= x=\frac{5}{3}\\\\9=3x-x^2=x=\frac{3}{2}-i\frac{3\sqrt{3}}{2},\:x=\frac{3}{2}+i\frac{3\sqrt{3}}{2}\\\\3x-y<7=x<\frac{7+y}{3}\\\\9+4=13$
