Question

(19-51)-(x-23)=-6

b-5x-10(-7)=55

c,-7-2x=-37-(-26)

d,|2x-1|=|-5|

e,2-|x+5|=7

h,(x+8)²=25

f,(x+3)³:3-1=-10

Answer 1

a, (19-51)-(x-23)=-6

19-51-x+23=-6

-32-x+23=-6

-32-x=-6-23

-32-x=-29

x=-32+(-29)

x=-61

-5x-10(-7)=55

-5x+70=55

-5x=55-70

-5x=-15

x=-15:(-5)

x=3

c, -7-2x=-37-(-26)

-7-2x=-37+26

-7-2x=11

-2x=11+7

-2x=18

x=-9

d, /2x-1/=/-5/

2x-1=5

2x=5+1

2x=6

x=6:2

x=3

e, 2-/x+5/=7

2-x+5=7

2-x=7-5

2-x=2

x=2-2

x=0

h, (x+8)²=25

(x+8)²=5²

x+8=5

x=5-8

x=-3

f, (x+3)³:3-1=-10

(x+3)³:3=-10+1

(x+3)³:3=-9

(x+3)³:3=3³

x+3:3=3

x+3=9

x=9-3

x=6
