I'll brainlist youuu plzzz quick

a) 4*r/9 = 4r/9

b) 5*m+13*n = 5m+13n

c) (6*c*t)-(3*p*4) = 6ct-12p

d) 8/k+3 = 8/f(k+3)

Step-by-step explanation:

i hope this helped!! :)

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
