Two equivalent expressions are shown in equation where k and h are both integer. k(5n + 4) = h + 20n What is the values of k and h?
A. k=4; h=16
B. k=9; h=7
C. k=2; h=6
D. k=4; h= 8

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,

nope.   happens to me as well.

where is the graph? need more info

okey so the slope is -3/5 and the y -intercept is 7/5

hope this if needed hmu
