Question

4×+6/y=15 and 6×-8/y=14 solve the equation with substitution method

Answer 1

Answer:

corrections are not right

Answer 2

ANSWER

The given system of equation is

4x+

y

6

=15 ..(i)

6x−

y

8

=14 .(ii)

Multiplying equation (i) by 4 and equation (ii) by 3, we get

16x+

y

24

=60 ..(iii)

18x−

y

24

=42 (iv)

Adding (iv) and (iii), we get

34x=102⇒x=3

Putting x=3 in equation (i), we get

12+

y

6

=15⇒y=2

Hence, the solution of the given system of equations is x=3,y=2

Putting x=3,y=2 in y=px−2, we get

2=3p−2⇒p=4/3.
