18) Solve the system. 0.4x - 0.1y = 2 0.2x + 0.5y = 1 A) (5, 0) B) (0, 5) C) (-5, 0) Eliminate D) (3, -10) please help me its ex
Artemon [7]
To solve the set of equations given above, we can use the substitution method where we substitute one equation to the other and solving for one variable. We do as follows:

<span>0.4x - 0.1y = 2
x = 5 + 0.25y

0.2x + 0.5y = 1
</span>0.2(5 + 0.25y)+ 0.5y = 1
y = 0
x = 5

Therefore, the correct answer from the choices is option A, (5,0).
