<h2>
D) X = 16/3 - 4y/3 </h2>
Explanation
3x + 4y = 16
3x = 16 - 4y
3x = 4 ( 4 - y)
x = 4(4 - y)/3
X= 16 /3 - 4y/3
Answer:
3x + 4y = 16 The rule is you can do any valid operation on both sides of an equation and it will still be equal. Subtract 4y.
3x = -4y + 16 Divide by 3.
x = -4y/3 + 16/3 Answer B.
