Question

Solve the following system of linear equations by substitution method:
    2x – y = 2
    x + 3y =15
​

Answer 1

Answer:

x = 3, y = 4

Step-by-step explanation:

2x - y = 2 ------> eq 1.

- y = 2 - 2x

y = 2x - 2

x + 3y = 15 -------> eq 2.

Substitute y = 2x - 2 in eq 2,

x + 3 ( 2x - 2 ) = 15

x + 6x - 6 = 15

7x - 6 = 15

7x = 15 + 6

7x = 21

x = 21 / 7

x = 3

Substitute x = 3 in eq 2,

2 + 3y = 15

3y = 15 - 2

3y = 12

y = 12 / 3

y = 4
