Question

3y - x = 4
y + 2x = -1
choose the correct graph of given the system of equations/ find any solutions if any.

Answer 1

perhaps you should give us a graph?

Answer 2

3y - x = 4 => x = 3y-4 --(1)
y + 2x = -1 => y+2x =-1--(2)
put (1) into (2)
y + 2(3y-4) = -1
7y = 7
y=1
put y=1 into (1)
x= 3(1)-4 = -1
therefore x=-1 and y=1
