Question

resolver as equações abaixo

Answer 1

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

2(x-3)=-3(12x-4)
2x-6=-36x+12
2x+36x=12+6
38x=18
x=18/38
x=6/12
x=3/4

4(5x-3)-64(3-x)-3(12x-4)=0
20x-12-192+64x-36x+12=0
20x+64x-36x=12-12+192
48x=192
x=192/48
x=4

5(x+1)+6(x+2)=9(x+3)
5x+1+6x+12=9x+27
5x+6x-9x=27-1-12
2x=14
x=14/2
x=7
