6a + 2 = 4(a + 5)
6a + 2 = 4a + 20
6a - 4a = 20 - 2
2a = 18
a = 18/2
a = 9

6a + 2 = 4(a + 5)
6a + 2 = 4a + 20
6a - 4a = 20 - 2
2a = 18
a = 18/2 = 9
a = 9

6a + 2 = 4(a+5)
6a + 2 = 4a + 20
6a - 4a = 20-2
2a = 18
a = 18/2
a = 9

6a + 2 = 4 (a + 5)
distribute
6a + 2 = 4a + 20
subtract 4a for both sides
2a + 2 = 20
subtract 2 for both sides
2a = 18
divide 2 for both sides
a = 9

6a + 2 = 4(a + 5)
multiply (a+5) by 4 and so you have:
6a + 2 = 4a + 20
Take 4a to the other side, and the the 2 to the other
side
6a - 4a = 20 - 2
combine like terms
2a = 18
Divide by 2
a = 18/2
a = 9
Now go relax....

6a + 2 = 4(a+5)
6a + 2 = 4a + 20
transpose +4a and +2 ... it will be negative
6a - 4a = 20 - 2
2a = 18
divied both sides by 2
a = 9

6a+2=4(a+5)
6a+2=4a+20 multiply 4 to both side of the equation.
6a-4a=2-20 transpose 4a and 2, they are both positive, so it will become negative.
2a=18 divide both of the equation to get the right answer, by 2.
2a/2=18/2
a=9
checking:
6(9)+2=4(9)+20
54+2=36+20
56=56

That will equal, after the Distributive Property, 6a + 2 = 4a + 20
From here move 4a to the other side by minusing 4a from both sides and do the same with the 2 to the side with the 20.
So, 2a = 18
Divide each side by 2.
a = 9
Simple.
