Question

3x+2y=7,4x-y=13 eliminating method

Answer 1

Step-by-step explanation:

3x+2y=7 ---- equation 1

4x-y =13 -----equation 2

Multiiply equation 1 with '1' and equation 2 with '2'

3x+2y=7 ----- equation 1

8x-2y=26 ------ equation 2

-----------------------------------------------------------------

Adding 11x =33

x=3

Putting value of x in equation 1

3(3)+2y=7

9+2y=7

2y = -2

y= -1

Answer - x=3 and y = -1
