Answer:
One solution
Step-by-step explanation:
As a generalization: an equation of degree n has n solutions. A quadratic equation has the second degree and thus two a solutions; a third degree equation has three, and so on. Thus, a first degree (linear) equation has one solution.
Answer:
(7,10)
Step-by-step explanation:
Well, to get the answer, we just divide 370 by 10.
370 divided by 10 = 37
So, the answer is 37
