Answer:
[tex]x \leq \frac{7 - x}{3}[/tex]
Step-by-step explanation:
This expression is an inequality which is a relation that makes a non-equal comparison between two numbers/expressions
we want x to be alone in one side, y + 3x ≤ 7
Subtract y from both sides,
y + - y + 3x ≤ 7 - y
3x ≤ 7 - y
divided both sides by 3 to get x alone
3x / 3 ≤ 7 - y / 3
x ≤ 7 - y / 3
