Answer:
x = 0
Explanation:
-(1.1x+2)+8=x+3(2.2x+2)
expand 3(2.2x+2) : 6.6x+6
3(2.2x+2)
apply distributive law: a(b+c)= ab +ac
a=3, b=2.2x, c=2
= 3·2.2x+3·2
simplify 3·2.2x+3·2 : 6.6x+6
multiply the numbers: 3·2.2=6.6
= 6.6x+3·2
multiply the numbers: 3·2=6
=6.6x+6
-1.1x+6=x+6.6x+6
add similar elements: x-6.6x=7.6x
-1.1x+6=7.6x+6
expand -(1.1x+2)+8: -1.1x+6
-(1.1x+2)+8
-(1.1x=2)+2): -1.1x-2
=-1.1x-2+8
Add/Subtractthenumbers:-2+8=6
=-1.1x+6
-1.1x+6=7.6x+6
move 6 to the right side
-1.1x+6=7.6x+6
Subtract 6 from both sides
-1.1x+6-6=7.6x+6-6
simlify
-1.1x=7.6x
move 7.6x to the left side
-1.1x=7.6x
subtract 7.6x from both sides
-1.1x-7.6x=7.6x-7.6x
simplify
-8.7x=0
divide both sides by -8.7
simplify
x=0
