Question

Is (4,2) a solution of the system y=x-2 and y=3x+4

Answer 1

The answer to your question is No, it is not a solution

Explanation:

Data

Point (4, 2)

y = x - 2 Equation l

y = 3x + 4 Equation ll

-Solve the system by equality

x - 2 = 3x + 4

-Solve for x

x - 3x = 4 + 2

- 2x = 6

-Result

x = 6/-2

x = -3

-Find y

y = -3 - 2

-Result

y = -5

The solution to this system is (-3, -5), (4,2) is not a solution.

Answer 2

False

Explanation:

y=x-2 y=3x+4

Substitute the point into both equations and see if it is true

2=4-2

2=2 true

and

2=3*4+4

2 = 12+4

2 =16

False

It is not a solution
