Question

solve the problem of linear equations by the elimination method X+Y=5 and 2x-3y=4​

Answer 1

Step-by-step explanation:

x + y = 5 - (i)

2x - 3y = 4 - (ii)

multiply 3 to eq (i)

3x + 3y = 15 - (iii)

adding (ii) and (iii)

2x - 3y = 4

3x + 3y = 15

_________

5x + 0 = 19

x = 19/5

putting x = 19/5 in eq (i)

19/5 + y = 5

y = 5 × 5/19

y = 25/19
