Question

15) Solve the following system of equations graphically.
a) x +y = 3, 2x + 5y = 12
b) x - 2y - 5 = 0, 3x - y = 15​

Answer 1

Answer:

x+y=3

x=3+y

now put values of y and you will get coordinates then present them on graph

2x+5y=12

x=12-5y/2

now 2*6=12therefore the equation is

x=6-5y

now put the values of y and you will get the value of x and now represent the graph

but if you don't know to draw graph i cannot do anything
