A system of equations is shown below: 5x + 2y = 3 (equation 1) 2x − 3y = 1 (equation 2) A student wants to prove that if equatio
nydimaria [60]

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:

5x+2y=3,\\\\2x-3y=1.

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

(5x+2y)+(2x-3y)=3+1,\\\\1\times (2x-3y)=1\times 1,

that is,

7x-y=4,\\\\2x-3y=1.

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.

You are adding to rational numbers with different signs. How can you tell if the sum will be positive, negative, or zero? #24
FrozenT [24]
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.
