4(7-x) = 5(x+2)
you would give 4 and 5 to everything in the parenthesis
28-4x = 5x+10
then subtract 10 on each side
28-4x = 5x+10
-10 -10
18-4x = 5x
then add 4x on each side
18-4x = 5x
+4x +4x
18 = 9x
x = 2

<em>ANSWER:</em>

<h2>x=2</h2>

<em>STEP:</em>

Multiply the parenthesis by the number before.

28-4x=5x+10

Add 4x to both sides.

28-4x=5x+10

28=9x+10

Subtract 10 from both sides.

18=9x

Divide both sides by 9.

2=x

We know that 1/25 is as much as 4/100 which can be written as 0,04.

Also 0,04 is as much as 4%.

I hope it'll help you :)
