Hello :
Simplifying
5x + 3y = 6
Solving
5x + 3y = 6
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3y' to each side of the equation.
5x + 3y + -3y = 6 + -3y
Combine like terms: 3y + -3y = 0
5x + 0 = 6 + -3y
5x = 6 + -3y
Divide each side by '5'.
x = 1.2 + -0.6y
Simplifying
x = 1.2 + -0.6y
Hello :
Simplifying
2x + -4y = 5
Solving
2x + -4y = 5
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4y' to each side of the equation.
2x + -4y + 4y = 5 + 4y
Combine like terms: -4y + 4y = 0
2x + 0 = 5 + 4y
2x = 5 + 4y
Divide each side by '2'.
x = 2.5 + 2y
Simplifying
x = 2.5 + 2y
good luck .

You can solve it with following method.
5x+3y=6 2x-4y=5
So 5x=6-3y so 2[(6-3y)/5]-4y=5
So x=(6-3y)/5 so 12-6y-20y=25
so -26y=25-12
so -26y=13
so y= -(1/2)
2x-4y=5
so 2x=5+4y
so 2x=5+4(-1/2)
so 2x=(10-4)/2
so 2x=6/4
so x =3/2
The value of x=3/2 and value of y= -1/2
Let me know if you need further assistance.

The question was how do I solve these linear equations on a Sharp EL-531WH calculator and not by hand.
