Question

Enter the solution (,) x , y to the system of equations shown.

y=5
y=2x+16

Answer 1

(2, 11)

Explanation:

So, we have to make them equal to each other.

5 = 2x + 16

Subtract 5 from both sides

y = 2x + 11

(2, 11)

Answer 2

The values of x and y are -5.5 and 5 respectively.

Using the system of equations given :

• y=5 ___(1)
• y=2x+16 ____(2)

Substitute y = 5 into (2)

5 = 2x + 16

5 - 16 = 2x

-11 = 2x

x = -5.5

From (2)

y = 2(-5.5) + 16

y = -11 + 16

y = 5

Hence, the values of x and y are -5.5 and 5 respectively.
