If by "coincide", in other words this is also known as intersect, it means that the solution to the system is that intersection point. For instance, if the intersection point of the 2 lines is (5,7) on the graph, it means that in both equations, x = 5 and y = 7. If you mean that the 2 equations result in the same line, it means that the 2 equations were really equal, but that one could be basic to be identical with the other. For example, if you have 2x + 2y = 8 and 4x + 4y = 16, they will give you the same line, and you can see that if you divide that second equation by 2 all the way crossways, it merely shows the first equation.
Answer would be -0.125 I think I hope so:)
Answer:
g = 11
Step-by-step explanation:
14g = 154
You have 14g. 14g means 14 times g. You want g alone. To get 14 alone, since g is being multiplied by 14, you must do the opposite operation. The opposite of multiplying by 14 is dividing by 14. The rule with equations is that you must do the same operation to both sides. Divide both sides by 14.
14g/14 = 154/14
g = 11
Answer:

multiply either sides by 3:

divide either sides by πr² :
