5c squared- d squared+3/2c - = -1. d= -4

For this case we have the following expression:

We must find the value of the expression when:

Substituting we have:

Finally, the value of the expression is:

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
