Answer 1
The solutions to the equation are (1. 5) and (4.6, -2.2)
How to determine the solution to the equation
From the question, we have the following parameters that can be used in our computation:
x^2 + y^2 = 26
2x + y = 7
The above expression is a system of equation that implies that:
One linear equation and one circle equation
Next, we plot the graph to solve graphically
The points of intersection are (1. 5) and (4.6, -2.2)
