Question

Solve for y 3x+6y=30

Answer 1

Answer:

the answer= y=5−x/2

Answer 2

Answer: $y=-\frac{1}{2} x+5$

Step-by-step explanation:

We need to isolate y by itself

Step 1) Subtract 3x from both sides

$3x+6y=30\\3x-3x+6y=30-3x\\6y=30-3x$

Step 2) Divide both sides by 6 to isolate y

$6y=30-3x\\\frac{6y}{6} =\frac{30}{6}-\frac{3x}{6} \\y=5-\frac{1}{2}x$
