Answer 1

Answer:

the value of x and y is -5

please tell of its wrong

Answer 2

Answer:

Simplifying

10y + x = 10x + y + -45

Reorder the terms:

x + 10y = 10x + y + -45

Reorder the terms:

x + 10y = -45 + 10x + y

Solving

x + 10y = -45 + 10x + y

Solving for variable 'x'.

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

Add '-10x' to each side of the equation.

x + -10x + 10y = -45 + 10x + -10x + y

Combine like terms: x + -10x = -9x

-9x + 10y = -45 + 10x + -10x + y

Combine like terms: 10x + -10x = 0

-9x + 10y = -45 + 0 + y

-9x + 10y = -45 + y

Add '-10y' to each side of the equation.

-9x + 10y + -10y = -45 + y + -10y

Combine like terms: 10y + -10y = 0

-9x + 0 = -45 + y + -10y

-9x = -45 + y + -10y

Combine like terms: y + -10y = -9y

-9x = -45 + -9y

Divide each side by '-9'.

x = 5 + y

Simplifying

x = 5 + y
