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 all ordered pairs (x,y) such that:
3x + 4y = 16
2x - 2y = 6
xm + yn = 28
ym + xn = 22
Find the ordered pair (m, n).
Find the ordered pair (m,n) which solves the following system of equations.2(-
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 three numbers is 78. If the first two numbers are doubled, the new sum is 128. Calculate the difference between the sum of the first two numbers and the third number
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.
