Question

Xby3 + 1by2 = 2by3 ??​

Answer 1

Answer: X=6 Y=36

Step by Step Explaination:

x/3+y/4=11,

5x/6−y/3=−7

Simplify the both equations:

3

x

+

4

y

=11⇒4x+3y=132 and

6

5x

−

3

y

=−7⇒5x−2y=−42

We have,

4x+3y=132...(1)

5x−2y=−42...(2)

Let us use elimination method to solve the given system of equation.

Multiply (1) by 2 and (2) by 3. And add both the equations.

23x=138

8x+6y=26415x−6y=−126

x=

23

138

=6

From (1):4(6)+3y=132

y=108/3=36

Answer x=6 and y=36
