Take the root of both sides and solve.
c = - 7 sqr root 5
c = -1.258

Answer:
x=7
y=11
z=7
Step-by-step explanation:
x + y + z = 25
y+z= 18
Z= 7
Substitute the third equation into the second
y+z=18
y+7 = 18
y = 18-7
y = 11
Now substitute y=11 and z=7 into the first
x +y+z = 25
x+11+7 = 25
x+18 = 25
x = 25-18
x=7
