Answer 4

Hello!
I have already answered a similar question that you posted a while ago.
Please follow the steps that I have shown you.
Remember:
Remove the parenthesis (Hint: change the signs of the terms inside the parenthesis if the parenthesis is preceded by a minus sign), combine like terms, transpose the constants to the right of the equation, and divide both sides of the equation by the numerical coefficient of the unknown.
You can only learn Algebra by doing the following secret:
Solve problems, then
Solve problems, then
Solve problems.
Translation: Practice, Practice, and Practice.
Bonus Solution:
Use distributive law on the following:
2(x + 3) - 6x - 4 = 8
2x + 6 - 6x - 4 = 8
4x +2 = 8
4x = 6
x = 6/4
or
x = 3/2
or
x = 1-1/2
or
x = 1.5
Good Luck!

Hey... It is much better to try to solve this simple problem!!!

Answer 6

x+(x+1)+(x+2)=9
x+x+1+x+2=9 (combine like terms)
3x+3=9 (subtract 3 from both sides)
3x=6 (divide both side by 3)
x=2

(y-2)+(y-1)+y= -3
y-2+y-1+y=3 (combine like terms)
3y-3=3 (add three to both sides)
3y=6 (divide both sides by 2)
y=2


19n-11-12n-5=5
19n-11-12n-5=5 (combine like terms)
7n-16=5 (add 16 to both sides)
7n=21 (divide both sides by 7

7h-17-6+4h=17 (*check to make sure this is the right problem)
7h-17-6+4h=17 (combine like terms)
11h-23=17 (add 23 to both sides)
11h=40 (divide both sides by 11)
h=40/11

-2t+3(2+t) = -10
-2t+6+3t=-10 (combine like terms)
t+6=-10 (subtract 6 from both sides)
t=-16

2(x+3)-6x-4 = 8
2x+6-6x-4=8(combine like terms)
-4x+2=8 (subtract 2 from both sides)
-4x=6 (divide both sides by -4)
x=-3.5

The rest you should be able to do yourself. Just remember if you do it to one side of the equal sign, you must also do the same thing to the other side of the equal sign.

4z+2(z+7)= -14

-5(1+w)+4w= 8

-3(2-y)+2y= 7

5a-(1-a)+4 = 9

-7 - (-3 - 2g) - 10 =0

1.5k - (k +2.4) = 17.4

3s - (0.5s+7.2) = 32.8

Answer 7

Looks that way!!!
Ok, look. You multiply through the entire parenthesis. You can add or subtract any portion from either side so long as you do it to the other side as well. In this way you isolate your unknown, and divide to produce your answer.
