Answer:
7x - 5y = -5 this is the standard form
Answer: -10
Step-by-step explanation:
If you put it in an equation it would be -7x=7(x+20). You would then -7x to both sides to get -14x=140. Just divide -14 on both sides to isolate x. This equates to -10. If you put -10 back into the equation then it says that 70 is 7 times larger than 10. Which it is.
Five times the sum of x and negative two, or five times the difference of x and two
The quotient of some number and four.
