Answer:

x=4, y=1

Step-by-step explanation:

We can solve this set of equations using elimination.

Multiply the first equation by 3:

[tex]15x-6y=54[/tex]

Multiply the second equation by 5:

[tex]15x+15y=75[/tex]

Now we take [tex](15x+15y=75)\\ - \\(15x-6y=54)[/tex]

[tex]21y=21[/tex]

Therefore, [tex]y=1[/tex].

To solve for x, substitute y=1 into the second equation.

[tex]3x+3y=15[/tex]

[tex]3x+3(1)=15[/tex]

[tex]3x+3=15[/tex]

[tex]3x=12[/tex]

Hence, [tex]x=4[/tex].
