Hey guyzz!! Good Morning:-)
Solve the following pairs of equations by reducing them to a pair of linear equations.
a) 1/2x + 1/3y = 2
1/3x + 1/2y = 13/6
Plss answer it fastly!!

1/2x + 1/3y = 2
1/3x + 1/2y = 13/6
Fractions are really annoying, so I will multiple 6 to both sides for both equations
3x + 2y = 12
2x + 3y = 13
Now I will multiply 2 to both sides of the top equation and 3 to both sides of the bottom equation
6x + 4y = 24
6x + 9y = 39
Now I subtract the lower equation from the upper equation
4y - 9y = 24 - 39
-5y = -15
y = 3
Now I plug this into the original equation
1/2x + 1/3y = 2
1/2x + 1 = 2
1/2x = 1
x = 2
This is by no means the fastest way to solve the problem, but it is safer and it's less likely to make a mistake.
(also how is it morning for u?)
