Answer: y = 11
Step-by-step explanation:
first, i collected the like terms.
7y + 9 = 4y + 42
then, i moved the terms.
7y - 4y + 42 - 9
then, i collected the like terms and calculated it.
3y - 33
finally, i divided both sides.
y = 11
Answer:
-5y + 12y + 9 = 4y + 42
Add like terms on the left side, -5y + 12y.
Subtract 4y from both sides.
3y + 9 = 42
Subtract 9 from both sides.
3y = 33
Divide both sides by 3.
