x=-2
Answer: CIRCLE C
Step-by-step explanation:
C. multiply the second equation by two. Then add the equations
Supply and demand affects prices which affects consumers want and likelihood of buying a product
The expression 36x² - 121 is in the 'difference of two squares form' which is (a² - b²)
Factorising (a² - b²) gives (a+b)(a-b)
Factorising 36x² - 121 gives (6x+11)(6x-11)
