Given equations are
y=x+4…..(1) and y=-x-6 …..(2)
equation (1) and (2) both equal to y so we can do equation (1)=equation (2) and find the valu of x
x+4=-x-6
x+x=-6-4
2x=-10
x=-5 using x valu in equation (2) we get the valu of y
y=x+4
y=-5+4
y=-1 the valu of (x,y) is (-5,-1) the option c is correct answer.
