So you subtitute y=3x into
2x+y=15
so
2x+(3x)=15
add like terms
5x=15
divide both sides by 5
x=3
subtitute x=3 into first equation (y=3x)
y=3(3)
y=9
T=0 is also a solution. Other than 0 here is a solution.
Make the denominators the same number. Then do the problem as you would regularly without fractions

Your answer is going to be 5x^2+6 because if you simplify and do x(5)x +6 it will equal to 5x^2 + 6
Hope this helped!!
