Question

Alguem sabe essas equações 10×-5=0
25×-100=0
6(×-6)=0
2×=-6

Answer 1

10×-5=0 ==> 10x = 5 ==. x = 5/10 ou x = 1/2
============================================
25×-100=0 ==> 25x = 100 ==. x = 4
=========================================
6(×-6)=0 ==. 6x - 36=0 ==> 6x = 36==. x = 6
=========================================
2×=-6 ==> x = - 3
