y+3.6=0.4(y+3)

Solution for y+3.6=0.4(y+3) equation:

Simplifying
y + 3.6 = 0.4(y + 3)

Reorder the terms:
3.6 + y = 0.4(y + 3)

Reorder the terms:
3.6 + y = 0.4(3 + y)
3.6 + y = (3 * 0.4 + y * 0.4)
3.6 + y = (1.2 + 0.4y)

Solving
3.6 + y = 1.2 + 0.4y

Solving for variable 'y'.

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

Add '-0.4y' to each side of the equation.
3.6 + y + -0.4y = 1.2 + 0.4y + -0.4y

Combine like terms: y + -0.4y = 0.6y
3.6 + 0.6y = 1.2 + 0.4y + -0.4y

Combine like terms: 0.4y + -0.4y = 0.0
3.6 + 0.6y = 1.2 + 0.0
3.6 + 0.6y = 1.2

Add '-3.6' to each side of the equation.
3.6 + -3.6 + 0.6y = 1.2 + -3.6

Combine like terms: 3.6 + -3.6 = 0.0
0.0 + 0.6y = 1.2 + -3.6
0.6y = 1.2 + -3.6

Combine like terms: 1.2 + -3.6 = -2.4
0.6y = -2.4

Divide each side by '0.6'.
y = -4

Simplifying
y = -4
