Question

Linear equations 3x+4y=7and 4x-y=3 by eliminating method

Answer 1

Answer:

3x+4y=7           equation 1

4x-y=3               equation 2

multiply equation 2 by 4

=16x-4y=12

By Elimination Method,

3x+4y=7

16x-4y=12

19x=19

x=19/19

x=1

Using this in equation   2

4(1)-y=3

4-y=3

-y=3-4

-y=-1

y=1
