If you mean: 4x -4y = 12 and -7x +4y = -36 then x = 8 and y = 5

7x-3y=21 Think of it this way. Block 3y or multiply 3(0)=0. Then you get: 7x=21 X=3 In vice versa, block 7x or multiply 7(0)=0 and look at: 3y=21 Y=7 So an ordered pair is (x,y) Thus, you get (3,7)
7x+3y=-52 3(8x-y=-74) 7x+3y=-52 24x-3y=-222 7x=-52 + 24x=-222 31x=-274 x=8.8387

The equation ( y = 7x ) defines a linear relationship between ( x ) and ( y ). To find ordered pairs that satisfy this equation, you can choose any value for ( x ) and calculate the corresponding ( y ). For example, if ( x = 1 ), then ( y = 7(1) = 7 ), giving the ordered pair ( (1, 7) ). Similarly, if ( x = 0 ), then ( y = 7(0) = 0 ), resulting in the ordered pair ( (0, 0) ). Other pairs could include ( (2, 14) ) and ( (-1, -7) ).
If you mean: y = 6x-4 and y = 7x-7 then by substitution x = 3 and y = 14
The equation y = 7x represents a linear relationship where the value of y is always 7 times the value of x. Therefore, all ordered pairs for this equation will have y as a multiple of 7x. For example, when x = 1, y = 7; when x = 2, y = 14; and so on. The ordered pairs for y = 7x will be in the form (x, 7x).
To find the solution to the system of equations ( y = 7x + 2 ) and ( y = 9x - 14 ), set the equations equal to each other: ( 7x + 2 = 9x - 14 ). Solving for ( x ), we get ( 16 = 2x ) or ( x = 8 ). Substituting ( x = 8 ) into either equation gives ( y = 58 ). Thus, the solution is the ordered pair ( (8, 58) ).
It is a pair of expressions -24 and 7x + 18 which are unrelated to one another.
To determine which ordered pair is a solution to the linear system defined by the equations ( xy = 2 ) and ( 7x - 4y = 8 ), you can test various pairs. For example, if you try the pair (2, 1), it satisfies the first equation (2 * 1 = 2) and also satisfies the second equation (72 - 41 = 14 - 4 = 10, which is not equal to 8). Therefore, you would need to check other pairs or solve the system algebraically to find the correct solution.
When you graph the equation [ y = 7x ], the graph is a straight line that passes throughthe origin and has a slope of 7.The x-y coordinates of every point on the line are an ordered pair that satisfies the equation.There are as many of them as there are points on a line ... an infinite number.Here are a few of them:(0, 0)(1, 7)(0.2, 1.4)(-9, -63)(137, 959)
