Answer:

Simplifying

5y + 2 = 3y + -4

Reorder the terms:

2 + 5y = 3y + -4

Reorder the terms:

2 + 5y = -4 + 3y

Solving

2 + 5y = -4 + 3y

Solving for variable 'y'.

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

Add '-3y' to each side of the equation.

2 + 5y + -3y = -4 + 3y + -3y

Combine like terms: 5y + -3y = 2y

2 + 2y = -4 + 3y + -3y

Combine like terms: 3y + -3y = 0

2 + 2y = -4 + 0

2 + 2y = -4

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

2 + -2 + 2y = -4 + -2

Combine like terms: 2 + -2 = 0

0 + 2y = -4 + -2

2y = -4 + -2

Combine like terms: -4 + -2 = -6

2y = -6

Divide each side by '2'.

y = -3

Simplifying

y = -3
