Answer:

x ≥ -4

Step-by-step explanation:

we can solve inequalities in the same way as equations except when multiplying or dividing by a negative; in which case you must reverse the inequality symbol

x - 7 ≤ 3x + 1

we can begin by adding 7 to each side to get:

x ≤ 3x + 8

now subtract 3x from each side to get:

-2x ≤ 8

we have to divide each side by -2 so we must reverse the symbol:

x ≥ -4
