Answer:
hope it's helpful.........
Answer:
i) y=-2x-7 and (ii) 2y-x=1
substitute i into ii
and solve for X
2(-2x-7)-x=1
-4x-14-x=1
-5x-14=1.........adding similar terms
-5x=15
X=-3......by dividing both side by -5
Then to solve for Y substitute X=-3 into one equation.
take eqn i) Y=-2(-3)-7
Y=6-7
Y=-1
in order pair form (X,Y)=(-3,-1)
