Question

Resolva as equações abaixo

10x +16=14× +8,,,,,

2× -6= -3× +9,,,,,,

20× - 12-192+64×-36× +12=96,,,,,

5× +5+6× +12=9× +27,,,,,

Answer 1

10x+16=14x+8
16-8=14x-10x
8=4x
8/4=x
x=2


2x-6=-3x+9
2x+3x=9+6
5x=15
x=15/5
x=3


20x-12-192+64x-36x+12=96
20x+64x-36x = 96+12+192-12
84x-36x=96+192
48x=288
x=288/48
x=6


5x +5+6x + 12= 9x+27
5x + 6x -9x = 27 -5 -12
11x - 9x = 27 - 17
2x = 10
x= 10/2
x= 5
