To solve the system of equations, we can use the method of substitution.
From the first equation, we can isolate y:
y = 1.8 - x
Substituting this expression for y into the second equation:
5x + (1.8 - x) = 1
5x + 1.8 - x = 1
4x + 1.8 = 1
4x = 1 - 1.8
4x = -0.8
x = -0.2
Substituting this value of x back into the first equation:
-0.2 + y = 1.8
y = 1.8 + 0.2
y = 2
Therefore, the solution to the system of equations is (-0.2, 2).
The correct choice is A.
Solve the system using any method.
x+y = 1.8 5x + y = 1
