1. Answer is x = 1
Explanation: Rearrange terms
-22 + 8c = 28x - 42
Add 22 to both sides of the equation
8x - 22 = 28x - 42
8x - 22 + 22 = 28x - 42 + 22
Simplify
8x = 28x - 20
Subtract 28x from both sides of the equation
8x = 28x - 20
8x - 28x = 28x - 20 - 28x
Simplify
-20x = -20
Divide both sides of the equation by the same term
-20x/-20 = -20/-20
2. Answer is x = -8
Rearrange terms
-11x - 2 = 6 - 10x
-11x - 2 = -10x + 6
Add 2 to both sides of the equation
-11x - 2 = -10x + 6
-11x - 2 + 2 = -10x + 6 + 2
Simplify
-11x = -10x + 8
Add 10x to both sides of the equation
-11x = -10x + 8
-11x + 10x = -10x + 8 + 10x
Simplify
-x = 8
Divide both sides of the equation
-x = 8
-x/-1 = 8/-1
Simplify
x = -8
3. Answer is x = 7
Rearrange terms
4x + 8 = -13 + 7x
Subtract 8 from both sides of the equation
4x + 8 - 8 = 7x - 13 - 8
Simplify
4x = 7x - 21
Subtract 7x from both sides of the equation
4x = 7x - 21
4x - 7x = 7x - 21 - 7x
Simplify
-3x = -21
Divide from both sides
-3x = -21
-3x/-3 = -21/-3
answer is x = 7
4. Answer is x = -15
Subtract 8 from both sides
2x + 8 = x - 7
2x + 8 - 8 = x - 7 -8
Simplify
2x = x - 15
Subtract x from both sides of the equation
2x = x - 15
2x - x = x- 15 - x
Simplify
x = -15
Tried to be detailed lol hope this helps!
Answer: x = 21
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
8x−2=6+10(x−5)
8x+−2=6+(10)(x)+(10)(−5)(Distribute)
8x+−2=6+10x+−50
8x−2=(10x)+(6+−50)(Combine Like Terms)
8x−2=10x+−44
8x−2=10x−44
Step 2: Subtract 10x from both sides.
8x−2−10x=10x−44−10x
−2x−2=−44
Step 3: Add 2 to both sides.
−2x−2+2=−44+2
−2x=−42
Step 4: Divide both sides by -2.
−2x / -2 = -42 / -2
x=21
