Explanation: Every hour Lucy gets paid $8 so if she works for 1 hour she gets $8 and for 2 hours of work she gets paid $16. It's just multiplying by 8.
Answer: The answer is (A) Show that the solution to the system of equations 7x − y = 4 and 2x − 3y = 1 is the same as the solution to the given system of equations
Step-by-step explanation: Given the following system of equations:

A student wants to prove that if equation 2 is kept unchanged and equation 1 is replaced with the sum of equation 1 and a multiple of equation 2, the solution to the new system of equations is the same as the solution to the original system of equations. He multiplied equation 2 by 1.
The new system of equations will be

that is,

Thus, the correct option is (A).Show that the solution to the system of equations 7x − y = 4 and 2x − 3y = 1 is the same as the solution to the given system of equations.
It will be zero if they are the same numbers like 12+-12=0 it will be negative if the negative is a higher number like -12+6=-6. it will be positive if the positive number is higher than the negative number like 12+-2=10.
