4x + 3(x - 2) = -(5x - 20) - x
First remove the parentheses carefully (watch the minus sign)
4x + 3x - 6 = - 5x + 20 - x
Combine like terms on both sides
7x - 6 = - 6x + 20
Add 6x and 6 to both sides
13x = 26
Divide both sides by 13
x = 2
a + 4 = 36 - 5a
6a = 32
a = 32/6 = 16/3

4x+3(x-2) = -(5x-20) - x
First, get rid of the parentheses.
4x + 3x - 6 = -5x + 20 - x
Then, add (subtract) like terms.
7x - 6 = -6x + 20
Then move like terms to the same side.
7x + 6x = 20 + 6
Add.
13x = 26
Divide both sides by 13.
x = 2
a + 4 = 36 - 5a
a + 5a = 36 - 4
6a = 32
a = 32/6
a = 16/3

4x + 3(x - 2) = -(5x-20)-x
4x + 3x - 6 = -5x + 20 - x
7x - 6 = -6x + 20
7x = - 6x + 26
13x = 26
x = 2
a + 4 = 36 - 5a
4 = 36 - 6a
0 = 32 - 6a
32 = 6a
a = 16/3 or 5.333333333333333333333333333333333333etc.

4x+3(x-2) = -(5x-20)-x
4x+3x-6 = -5x+20-x
7x-6=-6x+20
13x=26
x=2
a+4=36-5a
6a=32
a=32/6
a=16/3 or a=5.33

4x+3(x-2)=-(5x-20)-x
4x+3x-6=-5x+20-x
Now combine like terms:
7x-6=-6x+20
13x=26
x=2

that is basic, basic algebra, you shouldn't ask those questions in a web site where people ask about how to built rockets to go to the moon, Hit the books and try a little bit harder
