Question

Solve the systems of equations 3x – y = 3; 8x + y – 15 = 0​

Answer 1

Answer:

Ahoy user!

The answer:-

7x+11y = 3. ..( I )

8x+y = 15. ..(ii)

From, equation  (ii) we can write ,

y= 15-8x

Now, Putting the value of y in eq (i) we get,

7x + 11(15-8x) = 3

= 7x + 165 -88x = 3

= -81x = 3-165

=> -81x = -162

=> x = -162÷-81

=> x = 2

Putting the value of x in the substitution of y we get,

y=15-8x

y = 15 -8×2

= 15-16

y=> -1

hope this helps!

Good day!
