Answer:
1. 3x - 14 = 1
3x = 1 + 14
3x = 15 (divide both sides by 3 to get x)
3x/3 = 15/3
x = 5
2. Solving
7 + -5x = 22
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + -5x = 22 + -7
Combine like terms: 7 + -7 = 0
0 + -5x = 22 + -7
-5x = 22 + -7
Combine like terms: 22 + -7 = 15
-5x = 15
Divide each side by '-5'.
x = -3
Simplifying
x = -3
3. (4x+8)-5=-9
We move all terms to the left:
(4x+8)-5-(-9)=0
We add all the numbers together, and all the variables
(4x+8)+4=0
We get rid of parentheses
4x+8+4=0
We add all the numbers together, and all the variables
4x+12=0
We move all terms containing x to the left, all other terms to the right
4x=-12
x=-12/4
x=-3
4. -2x+9+8=25
We move all terms to the left:
-2x+9+8-(25)=0
We add all the numbers together, and all the variables
-2x-8=0
We move all terms containing x to the left, all other terms to the right
-2x=8
x=8/-2
x=-4
5. 7x-12=3+4x
We move all terms to the left:
7x-12-(3+4x)=0
We add all the numbers together, and all the variables
7x-(4x+3)-12=0
We get rid of parentheses
7x-4x-3-12=0
We add all the numbers together, and all the variables
3x-15=0
We move all terms containing x to the left, all other terms to the right
3x=15
x=15/3
x=5
