Answer:
Hello! I hope I’m correct!! :)
1. n = -4
2. y = 40
Step-by-step explanation:
Steps for the first equation.
Step #1. {we are solving for “2(9n-1)+7(n+6)=-60”}
[tex]18n-2+7n+42=-60[/tex]
Step #2. Simplify.
[tex]25n+40=-60[/tex]
Step #3. Subtract 40 {from both sides}
[tex]25n=-60-40[/tex]
Step #4. Simplify.
[tex]25n=-100[/tex]
Step #5. Divide both of the sides by 25. Which will be:
[tex]-\frac{100}{25}[/tex]
Step #6. Now divide (simplify) 100 & 25 which will give you the answer.
[tex]n=-4[/tex]
So for the first equation the answer is n = -4

Now let’s solve the second equation.
Step #1. Expand
[tex]-y+49=9[/tex]
Step #2. Subtract 49 from both sides.
[tex]-y+49-49=9-49[/tex]
Step #3. Simplify.
[tex]-y=-40[/tex]
Step #4. Divide both sides by -1.
[tex]-40/-1[/tex]
Step #5. Simplify.
[tex]y=40[/tex]
And your answer to the second equation would be y = 40
Sorry if this is incorrect but I hope this helps! If you have any questions about this, feel free to ask! Have a wonderful day! (≧∇≦)
