Answer:
Step-by-step explanation:
Given
(3x - 3) / 5 = (2x - 2) / 4
Begin by cross multiplying
Solution
- 4(3x - 3) = 5(2x - 2) Use the distributive property to remove brackets
- 12x - 12 = 10x - 10 Add 12 to both sides.
- 12x = 10x - 10 + 12 Combine the right
- 12x = 10x + 2 Subtract 10x from both sides
- 12x-10x = 2 Combine the left
- 2x = 2 Divide by 2
- x = 2/2
- x = 1
Note: the original equation gives you 0/5 = 0/4 which is 0 = 0.
