Y = 2x + 3<br> y = -2x + 15<br> Can you please explain how to get the answer.
-Dominant- [34]

Answer:

x = 3 and y = 9

Step-by-step explanation:

Given:

y = 2x + 3 .......................... equation i

y = -2x + 15 ........................ equation ii

since y is equals to the two functions , we can equate the two values of y . That is , equate equation i and ii , we have

2x + 3 = -2x + 15

Add 2x to both sides , we have

2x + 2x + 3 = -2x + 2x + 15

4x + 3 = 15

subtract 3 from both sides , we have

4x = 12

divide both sides by 4 , then

x = 3

substitute x = 3 into equation i to get the value of y , that is

y = 2(3) +3

y = 6 + 3

y = 9

Therefore :

x = 3 and y = 9
