Answer:
-1 8/9
Step-by-step explanation:
w + ( - x)
w = -5/9
z = 4/3
Input:
-5/9 + ( -4/3)
-5/9 - 4/3
-4/3 * 3/3 = -12/9
-5/9 - 12/9 = -17/9 = -1 8/9

Answer:
Step-by-step explanation:
Whenever one of the equations gives an expression for one of the variables, it is useful to use that expression to substitute into the other equation.
Using the expression for y and substituting into the second equation, we have ...
3x -5(2 +1/4x) = -3
3x -10 -5/4x = -3 . . . . . . eliminate parentheses
7/4x = 7 . . . . . . . . . . . . . add 10, collect terms
x = 4 . . . . . . . . . . . . . . . . .multiply by 4/7
y = 2 + (1/4)(4) = 3
The solution is (x, y) = (4, 3).
Answer:
Begin at the point, draw a vertical line either up or down to the x-axis to get the x-coordinate.
Begin at the point, draw a horizontal line either to the left or right of the y-axis to get the y-coordinate.
Step-by-step explanation:
In a two-dimensional plane, coordinates of a point define its exact location. The coordinate plane has two axes that are perpendicular to each other which are known as the x and y axis.
To find out the coordinates of a point in the coordinate system, follow the following procedure.
Begin at the point, draw a vertical line either up or down to the x-axis to get the x-coordinate.
Begin at the point, draw a horizontal line either to the left or right of the y-axis to get the y-coordinate.
The x-coordinate and the y-coordinate determine the new coordinates of a point.
The domain is all real numbers.
