Question

Chapter = Linnear simulation equation. Please answer it fast whose answer is correct I give it brainlieast answer



Please solve this Q. Using substitution method​

Answer 1

Rewriting the above equations in the standard form of ax + by = c

8x + 5y = 11 (i)

3x – 4y = 10 (ii)

In this problem, we will eliminate ‘y’ from both the equations (i) & (ii),

Note: - We can eliminate any one of the variable, to eliminate y, we have to make the coefficient of y in both the equations equal.

We have to multiply the coefficient of y with such a number that makes them equal to the common factor of both of them.

Multiply equations (i) with 4 and (ii) with 5 .

⇒ x = 2, putting the value of x = 2 in equation (i), we get y = - 1

Hence the solution of the two linear equation is x = 2 and y = - 1
