Question

Como resolve essas equações x-5=-2x22 2x+8=0 5x-4=6x+8 2x-8=3x-10 18x-43=65 23x-16=14-17x 10y-5(1+y)=3(2y-2)-20 (x-5)+(1-2x)=(3-x)

Answer 1

x-5=2.22
x=44+5
x=49

2x+8=0
2x=-4

5x-4=6+8
5x-6x=8+4
x=12

2x-8=3x-10
2x-3x+-10+8
x=-12

18x-43=65
18x=65+43
x=6

23x-16=14-17x
23x+17x=14+16
40x=30
x=3/4

10y-5-5y=6y-6-20
10y=5y-6y=-6-20+5
x=21

x-2x+5-10x=3-x
x+x-2x=10x=3-5
10x=-7
x=-7/10

Espero ter ajudado! Bons estudos!
