Question

how many solution of linear equation 2x +5y=7 explain

Answer 1

2x + 5y = 7

Since it's a linear equation in two variables, there will be infinitely many solutions. We can solve them by substituting any value for any one of the two variables. One such solution of the above equation is given below.

(We will be substituting the value for y)

When y = 2,

2x + 5*2 = 7

2x + 10 = 7

2x = 7 - 10

2x = -3

x = -3/2

Hope it helps :)
