Answer:
A
Step-by-step explanation:
Given the 2 equations
- 2x + 4y = 48 → (1)
x + 4y = 24 → (2)
Subtracting (2) from (1) term by term will eliminate the y- term, that is
- 3x = 24 ( divide both sides by - 3 )
x = - 8
Substitute x = - 8 into either of the 2 equations and solve for y
Substituting in (2)
- 8 + 4y = 24 ( add 8 to both sides )
4y = 32 ( divide both sides by 4 )
y = 8
Solution is x = - 8, y = 8 → A
