can you solve the system of equation by graphing

Question

x+y=8, x-y=6

Answer 1

Given linear equations are x+y = 8 and x-y = 6

First equation is y = -x+8

second equation is y = x

To find the coordnate points of lnear equations.

Substitute x = 0,1,-1 respectivvely in above equations.

First equation points are (0,8), (1,7), (-1,9)

Second equation points are (0,-6), (-1,-7)(1,-5)

Graph of equations

Draw a coordinate plane.

Plot the ponts of each equations.

Connect the points.

Observe the graph two lines are intersecting at ( 7,1)

Solution from the graph is x= 7, y = 1.
