Rearrange the first equation: x=8-2y. Plug in this value of x into the second equation: 2(8-2y)+y=7. Simplify: 16-4y+y=7. -3y=-9. y=3. Plug this value of y into the first equation: x+2(3)=8. Solve for x: x=8-6. x=2. The answer is {2,3)

What is the ordered pair for y equals -2x plus 4?
There are an infinite number of ordered pairs. Any point on the straight line which passes through (0,4) and has a gradient of -2 will be an ordered pair for the equation.
What are the order pairs for 2x plus y equals 1 and 2x - y equals -5?
These are equations of two straight lines. Provided the equations are not of the same or parallel lines, there can be only one ordered pair. So the answer is - (not are) : (-1, 3).
What are the order pairs for x equals y plus 3 and 2x plus y equals -3?
The answer is - not are - (-6, 9).
What is the ordered pair of 4x-4y plus 7 equals 15 8y equals 2x plus 14?
(5,3)
What are the ordered pairs for 2x plus 6y equals 6 3x minus 2y equals28?
Solving the simultaneous equations: x = -237/11 and y = 90/11
1- Which of the ordered pairs is a solution of 2x plus 3y equals 13?
2x plus 3y
What are the ordered pairs of 2x plus 5y equals 16 -x plus y equals -1?
(x, y) = (3, 2)
