4x + y - 30 =04x + y = 30
Let x = 5
4 ×5 + y = 30
y = 30-20
y = 10
let x = 10
4×10 + y = 30
y = 30-40
y = -10
let x = 9
4 × 9 + y = 30
y = 30 - 36
y = -6
This equation has infinitely many solutions. Every point on the line create by these points are the solution of the linear equation in two variable in which we can find rational and irrational numbers.

Thank you so much
Your welcome!!!
this equation has infinite solutions as you get any value of x by putting any value of y; if it is a LINEAR SIMULTANEOUS equation; then plotting those points on graph will always and always make a straight line;if it satisfies in (0,0)then it will pass through origin,else not....any point on line is it's solution
