16 - 2 (calculate)
14
The values of (x, y) are (-5, 1), if the equations
and
are solved by elimination method.
Step-by-step explanation:
The given is,
................................(1)
.....................................(2)
Step:1
Equation (2) is multiplied by -1 ( Eqn (2) × -1 )
..................................(3)
Step:2
Substrate the equation (1) and equation (3),


( - )
After the Subtraction equation becomes,




Step:3
By using y value find value of x,




Step:4
Check for solution,



Both sides are equal so answer is corrected
Result:
The values of (x, y) are (-5, 1), if the equations
and
are solved by elimination method.
Answer: C. The temperature decreased by 6 degrees.
