` 5x + 2y = 31`
` 3x + 7y = 36`

In the following question, two equations are given in variables X and Y. You have to solve these equations and determine the relation between X and Y. A) 5x + 2y = 31 B) 3x + 7y = 36

Solve the following paris of linear (simultaneous) equation using method of elimination by substution: 2x + 7y = 39 3x + 5y = 31

Let's add : 4xy + 5x + 7y, - 4xy - y - 3x, 3xy - 3y + 2x

If (0, a) and (b, 0) are the solutions of the following linear equations. Find ‘a’ and ‘b’. (i)8x - y = 34 (ii) 3x = 7y - 21 (iii)5x - 2y + 3 = 0

If (0, a) and (b, 0) are the solutions of the following linear equations. Find ‘a’ and ‘b’. (i)8x - y = 34 (ii) 3x = 7y - 21 (iii)5x - 2y + 3 = 0

Solve : (3x + 2y - 7)^(2) + (5x + 7y - 13)^(2) = 0 , for real values of x and y.

Solve : (3x + 2y - 7)^(2) + (5x + 7y - 13)^(2) = 0 , for real values of x and y.

Add the following: (i) x – 3y – 2z , 5x + 7y – 8z , 3x – 2y + 5z
