Which statement is true about the equations
-3x + 4y = 12 and 1/4x-1/3y = 1

O The system of the equations has exactly one solution at (-8, 3).
O The system of the equations has exactly one solution at (-4, 3).
O The system of the equations has no solution; the two lines are parallel.
O The system of the equations has an infinite number of solutions represented by either equation.

Sagot :

The third option; solve the equation and get x=4+4/3y then substitute it into the first equation for x; -3( 4+4/3y) +4y=12 and solve to get no solution

Also, when you graph the two lines they are parallel
