Need help on difficult math question

Answer:
x = 3.99
Step-by-step explanation:
Simplifying
4y + -3x = 8
Reorder the terms:
-3x + 4y = 8
Solving
-3x + 4y = 8
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4y' to each side of the equation.
-3x + 4y + -4y = 8 + -4y
Combine like terms: 4y + -4y = 0
-3x + 0 = 8 + -4y
-3x = 8 + -4y
Divide each side by '-3'.
x = -2.667 + 1.33y
Simplifying
x = -2.66 + 1.33y
Answer:
x = 3.99
