Answer:
A system of linear equations usually has a single solution, but sometimes it can have no ... A system of linear equations has one solution when the graphs intersect at a point. ... one. If you find a root and your discriminant is <0 (which means the quadratic really ... P.S. you can't use the discriminant to check linear equations.
Step-by-step explanation:
3(4x - 4) + 1/2(8x - 6) + 2x - 3 = -144
12x - 12 + 4x - 3 + 2x - 3 = -144
18x - 18 = -144
18x = -126
x = -126/18
x = -7 Answer
Its C
