Solving simultaneous equations
1)If there are three variables in a simultaneous linear equation, then how many equations will be required to find out the values of all the three variables? 
  

2)State true or false: In equation 'ax + by + c = 0', a and b are called coefficients of the variables x and y. 
  

3)Solve the equations. i) 2x + 3y = 13 and ii) 2x + 5y = 19 
  

4)Solve the equations. i) 9x + 4y = -26 and ii) x + 2y = -6 
  

5)Solve the equations. i) -10x - 4y = -52 ii) 2x + 32y = 260
