Answer: [tex]y=-\frac{1}{2} x+5[/tex]
Step-by-step explanation:
We need to isolate y by itself
Step 1) Subtract 3x from both sides
[tex]3x+6y=30\\3x-3x+6y=30-3x\\6y=30-3x[/tex]
Step 2) Divide both sides by 6 to isolate y
[tex]6y=30-3x\\\frac{6y}{6} =\frac{30}{6}-\frac{3x}{6} \\y=5-\frac{1}{2}x[/tex]
