# Solve each of the following system of inequations in R Given and Let us consider the first inequality.  7x – 1 < –6

7x – 1 + 1 < –6 + 1

7x < –5   (1)

Now, let us consider the second inequality.    3x + 63 < 0

3x + 63 – 63 < 0 – 63

3x < –63 x < –21

x (–∞, –21) (2)

From (1) and (2), we get x (–∞, –21)

Thus, the solution of the given system of inequations is (–∞, –21).
