Answer: x = 3.2 + 0.6y

Step-by-step explanation: Simplifying

5x + -3y = 16

Solving

5x + -3y = 16

Solving for variable 'x'.

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

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

5x + -3y + 3y = 16 + 3y

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

5x + 0 = 16 + 3y

5x = 16 + 3y

Divide each side by '5'.

x = 3.2 + 0.6y

Simplifying

x = 3.2 + 0.6y
