Answer:
Serina should have solved for x in the second equation because it has a coefficient of 1.
Step-by-step explanation:
we have
----> equation A
---> equation B
we know that
To solve the system of equations in the most efficient way, solve for x equation B and then substitute the value of x in equation A
so
----> equation C
substitute equation C in equation A
![2(31-7y)+3y=18](https://tex.z-dn.net/?f=2%2831-7y%29%2B3y%3D18)
solve for y
![62-14y+3y=18\\11y=62-18\\11y=44\\y=4](https://tex.z-dn.net/?f=62-14y%2B3y%3D18%5C%5C11y%3D62-18%5C%5C11y%3D44%5C%5Cy%3D4)
Find the value of x
substitute the value of y in the equation C
![x=31-7(4)=3](https://tex.z-dn.net/?f=x%3D31-7%284%29%3D3)
The solution is (3,4)
therefore
Serina should have solved for x in the second equation because it has a coefficient of 1.
