System of Three Equations
Find the ordered triple (x, y, z) if x + y + z = 16; x - z = 10; and y + z = 9
SolutionIn order to make it feasible for teachers to use these problems in their classwork, no solutions are publicly visible, so students cannot simply look up the answers. If you would like to view the solutions to these problems, you must have a Virtual Classroom subscription.
Find the ordered pair (m,n) which solves the following system of equations.2(-
3x + 4y = 16
2x - 2y = 6
xm + yn = 28
ym + xn = 22
Find the ordered pair (m, n).
p is 12 more than a third of q, which is 12 less than half of p. Find the ordered pair (p, q)
If 2X + 3Y + 4Z = 100 and 5X + 7Y + 9Z = 242, find X + Y + Z.
The sum of p and q is 44. q is two more than twice p. Find the ordered pair (p, q).
The following is a system of equations in x and y, with a constant K.
x + 2y = K
x - y = 2
If K is an integer between 20 and 25 inclusive, find all K such that the system has integer solutions.
Find all ordered pairs (x,y) such that:
