Answer:
Explanation:
Find a number that 4 and 9 can both be divided into:
4: 4, 8, 12, 16, 20,24,28, 32, 36
9: 9, 18,27,36
Both 4 and 9 are factors of 36.
Multiply each term in the equation (4x - 6y = 10) by 9.
Multiply each term in the equation (9x + 2y = 7) by 4
4x - 6y = 10 becomes 36x - 54y = 90
9x + 2y = 7 becomes 36x + 8y = 28
Subtract the bottom equation from the top equation
36x - 54y = 90
- 36x + 8y = 28
-62y = 62
