1x+2y=5 find four solutions​

Mathematics

Answer:

Simplifying

1x + 2y = 5

Solving

1x + 2y = 5

Solving for variable 'x'.

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

Add '-2y' to each side of the equation.

1x + 2y + -2y = 5 + -2y

Combine like terms: 2y + -2y = 0

1x + 0 = 5 + -2y

1x = 5 + -2y

Divide each side by '1'.

x = 5 + -2y

Simplifying

x = 5 + -2y
