Tell whether the value is a solution of the inequality

Swap sides so that all variable terms are on the left-hand side. This changes the sign direction.

Subtract 4 from both sides.

Subtract 4 from 14 to get 10.

Divide both sides by -2. As -2 is <0, the inequality direction has changed.

Divide 10 by -2 to get -5.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
