All you need to do is divide 291 by 7. If the quotient is a whole number, then 7 would be a factor of 291.
Let's test it out then, look at the picture attached.
As you can see in the picture attached, there is a remainder, so this would mean that 7 is not a factor of 291.
Plug 4x=9 in for y:
10x=18-2(4x+9)
10x=18-8x-18
10x=-8x
18x=0
x=0
now plug 0 in for x:
y=4(0)+9
y=9
to check, plug x and y back into one of the equations to make sure they are right:
10(0)=18-2(9)
0=18-2*9
0=18-18
0=0
