1/3 is the same as 2/6, so we can rewrite this as:
-5/6 + 1/3 = -5/6 + 2/6
To add fractions, add the numerators:
-5 + 2 = -3
So, -5/6 + 2/6 = -3/6
This can reduce, since 3 and 6 are divisible by 3.
-3/6 = -1/2
Answer:
square roots fall under exponets
Step-by-step explanation:
5x + 4y = 2
-5x - 2y = 4
So if we add both the equations 5x will be eliminated.
5x + 4y - 5x - 2y = 4 + 2
4y - 2y = 6
2y = 6
y = 3
As y is 3
x will be
5x + 4 x 3 = 2
5x + 12 = 2
5x = -10
x = -2
