Question

Solve by the method of substitution
i) x - 1/3y = 6 and 2x + 3y = 23​

Answer 1

Given: 2x+3y=13  ------(1)

            4x+5y=23  ------(2)

From equation (1),

2x+3y=13

y=313−2x

Substitute the value of y in equation (2):

4x+5y=23

4x+5(313−2x)=23

12x+65−10x=69

2x=69−65

2x=4

x=2

Then substitute the value of x in equation (1):

2(2)+3y=13

4+3y=13

3y=13−4

3y=9

y=3

Therefore solution is x=2 ans
