Answer:
y=4
x=-1
Step-by-step explanation:
replace y
2x+6=-x+3
3x=-3
x=-1
y=2x+6
y=2(-1)+6
y=-2+6
y=4

Answer:
no solution
Step-by-step explanation:
the x value in a linear equation in slope intercept form represents the slope of the line, since both equations int the system have the same slope there is no solution.
Here a=1, b= -5 and c= -3
so the discrim. is b^2 - 4(a)(c), or (-5)^2 - 4(1)(-3) = 25 + 12 = 37.
Because the discrim. is +, you'll have 2 real, unequal roots.
