Answer:
Step-by-step explanation:
hello :
y= 5x + 9
y = -x +3
so : 5x+9 = -x+3
5x+x= 3-9
6x=-6
x=-6/6 = -1
Step-by-step explanation:
[tex]y = 5x + 9..(1) \\ y = - x + 3..(2) \\ from \: equations \: (1) \: and \: (2) \\ 5x + 9 = - x + 3 \\ 5x + x = 3 - 9 \\ 6x = - 6 \\ x = \frac{ - 6}{6} \\ \huge \: \: \: x = 1[/tex]
