Question

Find the solution set of 8x<7x+9

Answer 1

For this case we must resolve the following inequality:

$8x$

Subtracting $7x$ from both sides of the inequality we have:

$8x-7x$

Different signs are subtracted and the major sign is placed.

$x$

Thus, the solution is given by all values of x less than 9.

Answer:

(-∞, 9)
