Question

6. If A = -(2x + 3), B = -3(x – 2) and C = -2x + 7. Find the value of k if (A + B + C) = kx.

Answer 1

Answer:

A= -2X-3

B= -3X+6

C= -2X+7

A+B+C= -2X-3-3X+6-2X+7= -7X+10

SO -7X+10=KX ... (1)

KX+7X=10

(K+7)X=10

SO X=10/(K+7)

putting the value of X in equation (1)

{-7 ×10/(K+7)}+10=K×10/(K+7)

=>( -70+10K+70)/(K+7)=10K/(K+7)

=>10K=10K

in this procesure wo can't find the value of K

so you have to check the question is correct or not
