Question

Solve the system using any method.

What is the solution of the system of​ equations?

​(Simplify your answer. Type an ordered pair. Type an integer or a​ decimal.)

Answer 1

x + y = 2.9

3x + y = 2.7

Answer 2

The system of equations is not provided. Please provide the system of equations so that I can help you solve it.

Answer 3

To solve the system of equations:

x + y = 2.9 ----(1)
3x + y = 2.7 ----(2)

We can use substitution or elimination method.

Let's solve using the elimination method. We will eliminate the variable 'y':

Multiply equation (1) by -1 and equation (2) by 1:

-1(x + y) = -1(2.9)
1(3x + y) = 1(2.7)

Simplifying:

-x - y = -2.9 ----(3)
3x + y = 2.7 ----(4)

Add equations (3) and (4) to eliminate the y variable:

(-x - y) + (3x + y) = (-2.9) + (2.7)

Simplifying:

2x = -0.2

Divide both sides by 2:

x = -0.2/2
x = -0.1

Substitute the value of x into equation (1) or (2) to solve for y:

x + y = 2.9

Substituting x = -0.1:

-0.1 + y = 2.9

Adding 0.1 to both sides:

y = 3

Therefore, the solution to the system of equations is (x, y) = (-0.1, 3).

Therefore, the solution to the system of equations is (-0.1, 3).
