Solve for x in the following equation.
Example 1:
5 x - 6 = 3 x - 8
Subtract 3x from both sides of the equation:
2x-6=-8
Add 6 to both sides of the equation:
2x=-2
Divide both sides by 2:
x=-1
The answer is x = - 1
Check the solution by substituting -1 in the original equation for x. If the left side of the equation equals the right side of the equation after the substitution, you have found the correct answer.
Left side: 5(-1) - 6 = - 11
Right side: 3(-1) - 8 = - 11

Answer:
The difference between the two numbers is 48. The ratio of the two numbers is 7:3. What are the two numbers?
Step-by-step explanation:
Solution:
Let the common ratio be x.
Let the common ratio be x.
Their difference = 48
According to the question,
7x - 3x = 48
⇒ 4x = 48
⇒ x = 48/4
⇒ x = 12
Therefore, 7x = 7 × 12 = 84
3x = 3 × 12 = 36
Therefore, the two numbers are 84 and 36.
