Question

suppose y=2x-16 and y=x+2. what is the value of x?

Answer 1

Step-by-step explanation:

Set two equations equal to each other

2x -16 = x+2

x = 18

Answer 2

Answer:

18

Step-by-step explanation:

Make the two equations to each other by subbing out the y

2x - 16 = x + 2

Move the like terms to one side

Subtract x from both sides

2x - 16 = x + 2

-x          -x

x - 16 = 2

Add 16 to both sides

x - 16 = 2

 + 16   + 16

x = 18

X will have to be 18 for these equations to be true.
