Question

solve the following pair of linear equations =8x+5y=9 , 3x-3y-15=0.....ans plz

Answer 1

Answer:

Step-by-step explanation:

8x + 5y = 9 ----- (i)

3x - 3y -15 = 0

3x - 3y = 15 -----(ii)

(i)×3 24x + 15y = 27

(ii)×5 15x - 15y = 75

(i) +(ii). 39x = 102

x = 34/13

Substituting value of x in eqn (ii)

y = -31/13
