Answer:

The value of y in the solution of the system is [tex]y=1[/tex]

Step-by-step explanation:

we have

[tex]y=3x-5[/tex] -----> equation A

[tex]6x+3y=15[/tex] -----> equation B

substitute equation A in equation B

[tex]6x+3(3x-5)=15[/tex]

[tex]6x+9x-15=15[/tex]

[tex]15x=15+15[/tex]

[tex]15x=30[/tex]

[tex]x=2[/tex]

Find the value of y

[tex]y=3(2)-5=1[/tex]
