Question

Solve the following pair of linear equation by substitution method
2x+3y=11
2x-4y=-24

Answer 1

Answer:

by substitution method of linear equations

Step-by-step explanation:

solve equation 1

2x+3y=11

3y=11-2x

y=11-2x/3

Answer 2

1. 2x+3y=11

2.2x-4y=-24

subtract equation 2 from equation 1

we get

7y=35

hence, y=5

putting value of y in equation 1

we get

2x+3×5=11

2x+15=11

2x=11-15

2x=-4

hence,x=-2

x=-2 and y=5
