Question

The equations x+5y=10,
3x-y=1, x-5y=10,and 3x+y=1 are shown on the graph below.
Which approximate solution for the system of equations x+5y=10 and 3x+y=1?
A.(-0.3,2.1)
B.(-0.3,-2.1)
C.(0.9,-1.8)
D.(0.9,1.8)

Answer 1

The approximate solution for the system of equations x+5y=10 and 3x+y=1 is given by:

A. (-0.3,2.1).

What is a system of equations?

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the equations are:

• x + 5y = 10.

• 3x + y = 1 -> y = 1 - 3x.

Hence:

x + 5(1 - 3x) = 10.

-14x = 5

x = -5/14 = -0.3.

y = 1 - 3x = 3.1(approximately)

Hence option A is correct.
