Question

Use substitution to solve the linear system of equations.

6x + 4y = 14
y = 5

The solution to the system of equations is .
(5, -1)
(-4, 5)
(5, -4)
(-1, 5)

Answer 1

(- 1, 5 )

yeah you made it

Answer 2

(- 1, 5 )

Explanation:

substitute y = 5 into the other equation

6x + 20 = 14 ( subtract 20 from both sides )

6x = - 6 ( divide both sides by 6 )

x = - 1 and y = 5 ← given

solution (- 1, 5 )
