What is the solution to the system of equations below 2X minus Y equals 10 and Y equals -1/2 X plus 5

x = 2 , y = 4.

(2,4)

Step-by-step explanation:

Simultaneous equation:

2x - y = 10    E1

y = + 5    E2

Substitute equation 2 into equation 1 for the y value.

2x -   + 5  = 10

2x -   = 5

2x +   = 5

= 5

x = 2

Substitute the x value  into  equation 2.

y = + 5

y = -1 + 5

y = 4

b) well because you get well

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
