Answer:
Equation 2 of system divided by 2 on both sides then we get second equation of system 2.
Explanation:
We are given two equations
![2x+2y=14](https://img.qammunity.org/2020/formulas/mathematics/high-school/r95jhz9qgnqcujoch7j2ulx0gi2da0engz.png)
![-4x+6y=12](https://img.qammunity.org/2020/formulas/mathematics/high-school/perlxidkni4eg0x9f1i0r1fyfflll5nbc7.png)
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

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.
