Question 1035972: How many solutions does this linear system have?
y = x+ 2
6x – 4y = –10
one solution: (–0.6, –1.6)
one solution: (–0.6, 1.6)
no solution
infinite number of solutions

You can put this solution on YOUR website!
y = x+ 2
6x – 4y = –10
substitute the first into the second.
6x-4(x+2)= -10
6x-4x-8=-10
2x=-2
x=-1
y=1 One solution, (-1,1)
That is none of the choices above, but it is the right answer. Perhaps the choices were not correct or the equations are different from these.
