Step-by-step explanation:

1)3.25x + -1.5y = 1.25

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '1.5y' to each side of the equation.

3.25x + -1.5y + 1.5y = 1.25 + 1.5y

Combine like terms: -1.5y + 1.5y = 0.0

3.25x + 0.0 = 1.25 + 1.5y

3.25x = 1.25 + 1.5y

2)13x-6y=10

13x + -6y = 10

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '6y' to each side of the equation.

13x + -6y + 6y = 10 + 6y

Combine like terms: -6y + 6y = 0

13x + 0 = 10 + 6y

13x = 10 + 6y

Simplifying
3.25x + -1.5y = 1.25

Solving
3.25x + -1.5y = 1.25

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '1.5y' to each side of the equation.
3.25x + -1.5y + 1.5y = 1.25 + 1.5y

Combine like terms: -1.5y + 1.5y = 0.0
3.25x + 0.0 = 1.25 + 1.5y
3.25x = 1.25 + 1.5y

Divide each side by '3.25'.
x = 0.3846153846 + 0.4615384615y

Simplifying
x = 0.3846153846 + 0.4615384615y
