Question

Select the statement that correctly describes the solution to this system of equations.

2x = -y + 8
4x - 2y = 8
A. There is exactly one solution at (0, 8).
B. There is exactly one solution at (3, 2).
C. There is no solution.
D. There are infinitely many solutions
Dac

Answer 1

B ) Exactly one solution (3 , 2)

Explanation:

2x + y = 8 --- 1

4x - 2y = 8

2x - y = 4 ---- 2

4x = 12

x = 3

Putting the value of x in 1 , we get ,

2(3) + y = 8

y = 8 - 6 = 2
