Answer 2

Simplifying
5y + 4 = 4y + 5

Reorder the terms:
4 + 5y = 4y + 5

Reorder the terms:
4 + 5y = 5 + 4y

Solving
4 + 5y = 5 + 4y

Solving for variable 'y'.

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

Add '-4y' to each side of the equation.
4 + 5y + -4y = 5 + 4y + -4y

Combine like terms: 5y + -4y = 1y
4 + 1y = 5 + 4y + -4y

Combine like terms: 4y + -4y = 0
4 + 1y = 5 + 0
4 + 1y = 5

Add '-4' to each side of the equation.
4 + -4 + 1y = 5 + -4

Combine like terms: 4 + -4 = 0
0 + 1y = 5 + -4
1y = 5 + -4

Combine like terms: 5 + -4 = 1
1y = 1

Divide each side by '1'.
y = 1

Simplifying
y = 1
