3) distribute the 2
4) distrubute the negative
5) combine like terms
6-7) begin to solve for x
8) plug in the value solved for x in the other equation
9-11) solve for y
Final Answers:
x=5/7 y=4
Answer:
yes
Step-by-step explanation:
multiply 7x7 and you will get 49. Then do 49- 56 and you will get -7. So the statement is true.
The answer is a. n+19=65 n=46 $46. To find out how much more she needs to save, you would add that amount with 19 to get a total of 65. So your equation would be n+19=65. Then once you have your equation, solve it. Subtract 19 from both sides to get n by itself.
n+19=65
-19 -19
n=46
So your answer for how much more she needs to save is $46.
