Solution for 4+0.6(3-y)=0.3y-7(y-0.8) equation:


Simplifying
4 + 0.6(3 + -1y) = 0.3y + -7(y + -0.8)
4 + (3 * 0.6 + -1y * 0.6) = 0.3y + -7(y + -0.8)
4 + (1.8 + -0.6y) = 0.3y + -7(y + -0.8)

Combine like terms: 4 + 1.8 = 5.8
5.8 + -0.6y = 0.3y + -7(y + -0.8)

Reorder the terms:
5.8 + -0.6y = 0.3y + -7(-0.8 + y)
5.8 + -0.6y = 0.3y + (-0.8 * -7 + y * -7)
5.8 + -0.6y = 0.3y + (5.6 + -7y)

Reorder the terms:
5.8 + -0.6y = 5.6 + 0.3y + -7y

Combine like terms: 0.3y + -7y = -6.7y
5.8 + -0.6y = 5.6 + -6.7y

Solving
5.8 + -0.6y = 5.6 + -6.7y

Solving for variable 'y'.

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

Add '6.7y' to each side of the equation.
