Tanay obtained 98 marks in a mathematics test. His score is the highest in the class and it is also 8 more than three times the lowest score. Create the equation and calculate the lowest score.

Find three consecutive odd numbers whose sum is 159.

Solve 3x - 2y = 6 and 

Solve the following by substitution method 2x - 3y = 7 and x + 6y = 11.

Solve the following by using elimination method: 2x + y = 6 , 3y = 8 + 4x

Solve 2a – 3/b = 12 and 5a – 7/b = 1

Solve the following equations by using the elimination method: x - y = 1 , 3x - y = 9

Solve the following system of linear equations: 2x - 4y = 6 , x - 3y = 12

Solve: x - 2y = 8 , 4x + 2y = 7 by using elimination method.

For the solution of the system of equations above, what is the value of  ?

Note:
The equations can be solved in many other ways like substitution
method which is: to eliminate one variable in any one of the
equations with the help of other equation. As we need to find the
value of x, we try to find the value of y in terms of x from one
equation. Then put that value of y in the other equation to get a linear equation in one variable , which is x.
