Question

Solve the following simultaneous
equations
3x+y = 10 ; x-y=2​

Answer 1

Answer:

This is the answer for this question.

Answer 2

Answer:

The given equations are;

3x + y = 10 . . . .(1)

x - y = 2 . . . . . (2)

Now,

Adding equations (1) and (2), we get,

➜ 3x + y + x - y = 10 + 2

➞ 3x + x + y - y = 12

➞ 4x = 12

➞ x = 12/4

➞ x = 3

Now,

Putting the value of x = 3 in equation (2), we get

➜ x - y = 2

➞ (3) - y = 2

➞ 3 - y = 2

➞ - y = 2 - 3

➞ - y = - 1

➞ y = 1

∴ The value of x = 3, y = 1 is the solution of the system of the given equations.
