Find the solution to the system of equations,
x + y + z = 18
y+ z = 11
z = 8
A. x = 7, y = 3, z = 8
B. x = 7, y = 11, z = 3
C. x = 18, y = 3, z = 8
D. x = 18, y = 11, z = 8
A is the answer :) Since we are given z = 8, finding y is simple. By replacing the z in y + z = 11, we can see that y = 3 After finding these two, x can be found
