OLEGan [10]3 years ago

3x -3y = 6

or, 3(x -y)= 6

or, x-y =6/3

or, x-y = 2

or, x=2+y........eqn(i)

4x - 7y = 2

substituting the value of x from eqn(i)

or, 4(2+y) -7y = 2

or, 8 + 4y -7y = 2

or, -3y = 2-8

or, y = -6/-3

■ y=2

so in eqn(i)

x= 2+y

x= 2+2

■x = 4

Troyanec [42]

Answer:

Step-by-step explanation:

A.

R(x)=px=x(-45 x+1800)=-45 x²+1800 x

B.

C(x)=7000+100 x

C.

P(x)=R(x)-C(x)=-45 x²+1800 x-(7000+100 x)

or P(x)=-45x²+1800 x-100 x-7000

or P(x)=-45 x²+1700 x-7000
