5x+5׳✓8=6x-5׳√-27

-6x+√25÷(-5)=-4x+20÷√16

​

Answer 1

Explicación paso a paso:

#1

-5x-31=3x+25

-5x-3x=25+31

-8x=56

x=56/-8

x=-7

#2

-4x+12:2²=-2x+√169

-4x+12:4=-2x+13

-4x+3=-2x+13

-4x+2x=13-3

-2x=10

x=10/-2

x=-5

#3

5x+5׳✓8=6x-5׳√-27

5x+5•2=6x-5•-3

5x+10=6x+15

5x-6x=15-10

-x=5

x=-5

#4

-6x+√25÷(-5)=-4x+20÷√16

-6x+5÷(-5)=-4x+20÷4

-6x-1=-4x+5

-6x+4x=5+1

-2x=6

x=6/-2

x=-3
