Question

4. Solve this system of equations using any method.

2x – y = 5
4x + y = 7

(Points : 4)
(4, –3)
(4, –9)
(2, –1)
(2, –4)

Answer 1

the easiest to use here would be elimination
the y coefficients are already equal and opposite so just add the equations, solve for x then substitute that value of x in either given equation to find y

Answer 2

did you get C?
