Question

78x+91y=53 and 65x+117y=60 by elimination method

Answer 1

can you calculate this much by yourself

Answer 2

Concept:

Elimination method means to remove one variable by adding or subtracting the two equations and then finding the value of the variables.

Given:

We are given that:

78 x + 91 y = 53 and 65 x + 117 y = 60

Find:

We need to find x and y with the help of elimination method.

Solution:

78 x + 91 y = 53 and 65 x + 117 y = 60

First make the coefficient of x variable equal.

5070 x + 5915 y = 3445

5070 x + 9126 y = 4680

Subtracting the equations, we get:

3211 y = 1235

y = 0.3846

78 x + 91 y = 53

78 x = 53 - 34.99

x = 0.2309

Therefore, we get the value of x as 0.2309 and y as 0.3846.
