Question

solve the following pair of linear equations by substitution method y-5=0 3x+4y-20=0​

Answer 1

put y=5in equation and find c

Answer 2

Answer:

The value of x = 0

The value of y = 5

Step-by-step explanation:

Given,

y -5 = 0 and 3x+4y - 20 = 0

To find,

The solutions of this pair of linear equations by substitution method

Solution:

y -5 = 0 ---------------(1)

3x+4y - 20 = 0 ---------(2)

From equation (1) we have, y = 5

Substitute the value of 'y' in equation (2) we get

3x +4×5 -20 = 0

3x + 20 -20 = 0

3x = 0

x = 0

The value of x = 0

The value of y = 5
