If you need the number in fractional form after rounding to the nearest hundredth, put the decimal part over 100 and simplify. For example, turningpi into a fraction, start with 3.14. Rewrite as 3 and 14/100. Simplify to 3 and 7/50.

Answer:
x = 10
Step-by-step explanation:
Given the 2 equations
12x - 6y = 60
24x + 6y = 300

36x + 0 = 360
36x = 360 ( divide both sides by 36 )
x = 10
