Question Resolver y realizar la comprobacion del siguiente sistema de ecuacion aplicando el metodo grafico. [y=3-2x, y=8-7x

The solution for the system of equations: y = 3 – 2x and y = 8 – 7x, is x = 1, y = 1. In the question, we are given a system of equations, y = 3 -2x … (i), and y = 8 – 7x … (ii). We have been asked to solve the given system of equations. To solve the system of equations, we do as follows: Substitute the value of y = 3 – 2x, from (i) in (ii), to get: y = 8 – 7x, or, 3 – 2x = 8 – 7x, which is a linear equation in one variable. To solve this, we follow these steps: 3 – 2x = 8 – 7x, or, 3 – 2x + 7x = 8 – 7x + 7x {Adding 7x to both side of the equation}, or, 3 + 5x = 8 {Simplifying}, or, 3 + 5x – 3 = 8 – 3 {Subtracting 3 from both sides of the equation}, or, 5x = 5 {Simplifying}, or, 5x/5 = 5/5 {Dividing both sides of the equation by 5}, or, x = 1. Substituting x = 1, in (i), we get: y = 3 – 2x, or, y = 3 – 2(1), or, y = 3 – 2 = 1. Thus, the solution for the system of equations: y = 3 – 2x and y = 8 – 7x, is x = 1, y = 1.
