In the system of linear equations below, a and b are constants. the solution to the system is (5,1) ax+by=38

bx-ay=8

what are the values of a and b?
PLEASE HELP

Actually Welcome to the Concept of the linear equations..

Here given value of x= 5 and y =1 , so we get as,

5a + b = 38 and 5b - a = 8

so, now we multiply equation no. 2 by 5 all over.

==> 25b - 5a = 40....(1)

hence adding new equation and equation no. 1

26b = 78

b = 78/26

hence b = 3 , and a = 7

if this is really you s much. i only have 3 points left and i have 2 questions to ask
