Solve for x in 2nd equation
times -1 both sides
x-5=6y
add 5
x=6y+5
sub
5(6y+5)+4y=-26
30y+25+4y=-26
34y+25=-26
minus 25 both sides
34y=-51
divide both sides by 34
y=-3/2
sub back
x=6y+5
x=6(-3/2)+5
x=-18/2+5
x=-9+5
x=-4
(-4,-3/2) is solution
Step-by-step explanation:
The relation and its inverse (if it exists) must be symmetrical about the line y = x.
Hence the answer is the 2nd from the top.

Step-by-step explanation:
the answer is 458 because thats the right answer
We could do it by first writing

so that

and since
, we have

# # #
Alternatively, we can just compute the product and take it mod 4:

and so we get the same result of 1.
