Question 3 and 4 need help

#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!!
