Answer:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point. No solution.
Step-by-step explanation:
Answer is 9
you always simplify the paranthesis first and then do the rest.
(-7)(-2) is 14 and -15 divided by 3 is -5
so you have 14+(-5) which is just 14-5
it gives you 9
