#1
Solving by submitting method:
By first equation,
Now, we can find the original value of y from Eqⁿ (ii).
Now, we can find the original value of x , from Eqⁿ (I)
Therefore, the values of x and y are 5 and 1 respectively.
#2
Solving by Eliminating method:
Step 1: Multiply Eqⁿ (I) by 3 and Eqⁿ (ii) by 2 to make the coefficients of y equal. Then we get the equations.
Step 2: Subtract Eqⁿ (iii) from Eqⁿ (iv) , we get
Therefore, the pair of equations has no solution.
Hope this helps!!
