Question

4(x+9)= -36
7(1-x)=-49
-15(x+25)=32
-4(2x-1)=28
-8(x+13)=32
aflati pe x

Answer 1

a)4(x+9)=-36⇒4x+36=-36⇒4x=-36-36⇒4x=-72⇒x=-72/4⇒x=-18
b)7(1-x)=-49⇒7-7x=-49⇒-7x=-49-7⇒-7x=-56⇒x=-56/-7⇒x=8
c)-15(x+25)=32⇒-15x-375=32⇒-15x=375+32⇒-15x=407⇒x=407/-15
d)-4(2x-1)=28⇒-8x+4=28⇒-8x=28-4⇒-8x=24⇒x=24/-8⇒x=-3
e)-8(x+13)=32⇒-8x-104=32⇒-8x=104+32⇒-8x=136⇒x=136/-8⇒x=-17
sucees

Answer 2

4(x +9)=36
(X+9)=36:4=9
X=9-9
X=0

7(1-x)=49
(1-x)=49:7=7
X=7+1
X=8

-15(x+25)=32
(X+25)=32-15=17
X=25-17
X=8

-4(2x-1)=28
(2x-1)=24
X=25

-8(x+13)=32
(X+13)=24
X=24-13
X=11
