Question

in one day international match, Dhoni and Raina together scored 198 runs. express the statement in terms of linear equation in two variables.

Answer 1

let x be run by dhoni and y be run by raina

the linear equation is x + y =198

Answer 2

Concept: If an equation is written in the form ax + by + c=0, where a, b, and c are real integers and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero, then it is said to be a linear equation in two variables. For instance, the linear equations 10x + 4y = 3 and

-x+ 5y = 2 have two variables.

Given: Dhoni and Raina together scored 198 runs

To find: the statement in terms of linear equation in two variables

Solution: Let the runs scored by Dhoni = x

and the runs scored by Raina =y

Total runs scored = 198

According to question,

Dhoni and Raina together scored 198 runs i.e.,

x + y = 198

Hence, the statement in terms of linear equation in two variables is

x + y = 198
