The following proof shows an equivalent system of equations created from another system of equations. Fill in the missing reason
aev [14]

Answer:

Equation 2 of system  divided by 2 on both sides then we get second equation of system 2.

Step-by-step explanation:

We are given two equations

2x+2y=14

-4x+6y=12

We are given a proof which shows an equivalent system of equations created from another system of equations

We have to fill the correct reason in the blank space

Statement:2x=2y=14

-4x+6y=12

Reason: Given

Statement :2x=2y=14

-2x+3y=6

Reason : equation 2 of system I divided by 2 on both sides then we get second equation of system 2.

When we divide by 2 then the solution does not change and x and y - intercepts are not change.So, the two systems are equivalent.

(8 + 4) + 3 and (8 + 3) + 4.
