Solving
9.3 + 4y = 6.3 + 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.
9.3 + 4y + -3y = 6.3 + 3y + -3y

Combine like terms: 4y + -3y = 1y
9.3 + 1y = 6.3 + 3y + -3y

Combine like terms: 3y + -3y = 0
9.3 + 1y = 6.3 + 0
9.3 + 1y = 6.3

Add '-9.3' to each side of the equation.
9.3 + -9.3 + 1y = 6.3 + -9.3

Combine like terms: 9.3 + -9.3 = 0.0
0.0 + 1y = 6.3 + -9.3
1y = 6.3 + -9.3

Combine like terms: 6.3 + -9.3 = -3
1y = -3

Divide each side by '1'.
y = -3

Simplifying
y = -3
