To solve the system of equations, we can use the method of substitution.
First, we solve the first equation for y:
y = 4.9 - x
Now, substitute this expression for y in the second equation:
5x + (4.9 - x) = 4.5
Simplifying the equation:
5x + 4.9 - x = 4.5
4x + 4.9 = 4.5
4x = 4.5 - 4.9
4x = -0.4
x = -0.4/4
x = -0.1
Now substitute this value of x back into the first equation to solve for y:
y = 4.9 - (-0.1)
y = 5
Therefore, the solution to the system of equations is (-0.1, 5) or in decimal form, (-0.1, 5).
Answer: A. (-0.1, 5)
Solve the system using any method.
x+y=4.9
5x+y=4.5
