Question

11x+15y+23=0
7x-2y-20=0
​

Answer 1

Answer:

your question is

11x+15y+23=0. - eq1

7x-2y-20=0. - eq2

Step-by-step explanation:

now we'll eq1×2 + eq2×15

then we'll get

(11+105)x+(46-220)=0

116x-174=0

x=174/116

x=87/58

now we'll put the value of x in eq2

7×87/58-2y-20=0

609/58-2y=20

-2y=20-609/58

-2y=1160-609/58

y=551/58×2

y=551/116
