Question

HI PEOPLE. IM ON MY LAST QUESTION AND DONT get it. can someone help? this is the last question...
what is the solution of the system?
y= 13x - 1
y= 9x +4

Answer 1

Since both 13x-1 and 9x+4 are equal to y, they must be equal to each other.

13x - 1 = 9x + 4
13x - 9x = 4 + 1
4x = 5
x = 5/4

sub into either of the two equations, I will go with
y = 9x + 4
= 9(5/4)+4
= 45/4 + 16/4 = 61/4

Answer 2

THANK YOU
