3x - 4y = 7
Try to find by trial and error what numbers you can put in for "x" and "y" to get 7
Your answers are x=5 and y=2
Check to see if these are correct...
3(5) - 4(2) = 7
15 - 8 = 7
7-7 Correct!
There are an infinite number of ordered pairs that satisfy the equation.
(10, 2)
x = 12 y = 2 (12,2) satifies the equation
The ordered pair is (1, 3).
5x=4y=-20 x=-4 y=-5 (-4,-5) is the ordered pair
There are an infinite number of ordered pairs. (-5, -7) is one pair
(4.25, 0.25) is a solution.
7
There are an infinite number of ordered pairs that satisfy the equation.
There are infinitely many ordered pairs: each point on the straight line defined by the equation is an ordered pair that is a solution. One example is (0.5, 2.5)
(10, 2)
To determine if an ordered pair is a solution to an inequality, you need to substitute the values of the ordered pair into the inequality and check if the statement holds true. If the left side of the inequality evaluates to a value that satisfies the inequality when compared to the right side, then the ordered pair is a solution. If not, it is not a solution. Please provide the specific ordered pair and the inequality for a definitive answer.
(0, 6.5) is one option.
Substitute the values of the ordered pair into the relation. If the equation is valid then the ordered pair is a solution, and if not then it is not.
The equation 2x-5y=-1 has a graph that is a line. Every point on that line is an ordered pair that is a solution to the equation. So pick any real number x and plug it in. You will find a y and that pair (x,y) is an ordered pair that is a solution to this equation. For example, let x=0 Then we have -5y=-1so y=1/5 The ordered pair (0, 1/5) is a point on the line and a solution to the equation.
y=(-1) x=(2)
