Hey! Great to see you again.
Based on what we learned last time, we can apply it to this equation!
Solve 3x+y =−5 for y:
3x+y=−5
3x+y+−3x=−5+−3x Let us add -3x to both sides.
y=−3x−5.
Substitute −3x−5 for y in −2x+3y=18:
−2x+3y=18
−2x+3(−3x−5)=18
−11x−15=18 Simplify both sides :)
−11x−15+15=18+15 Add 15 to each side.
−11x=33
x = -3
Now solve for y.
−3 for x in y=−3x−5:
y=(−3)(−3)−5
Can you solve this equation? Let me know if you need help, tell me what you get! :) That will be your y answer. :D
Have a great one!
It's hard to tell from the way the question is written.
-- If he has 5 pennies, then it doesn't matter how many he lost.
He has five of them.
-- If he has 5 pennies after he lost three of them, then there are
eight now, just like there were before, but he only has 5 of them.
-- If he had 5 pennies before he lost three, then there are still
5 pennies, but he only has two of them.
