Evaluating the equation 3a +2b - 9p= 12c in a=3,b=3, and c=−7 we can see that p = 11
How to find the value of p?
Here we just need to evaluate the expression, which means, replacing the values of the variables by the correspondent numbers, and then solve the equation for p.
We can write:
3a +2b - 9p= 12c
Replacing:
a= 3
b = 3
c = -7
3*3 + 2*3 - 9p = 12*-7
9 + 6 - 9p = -84
15 - 9p = -84
15 + 84 = 9p
99 = 9p
99/9 = p
11 = p
