Question

3x-4y=10;
4x+3y=5

Please solve it By substitution method, with all steps​

Answer 1

${\huge {\mathfrak {Answer :-}}}$

➡️ 3x - 4y = 10

Or, 3x = 4y + 10

Or, x = (4y + 10)/3.

➡️ 4x + 3y = 5

Or, (16y + 40)/3 + 3y = 5

Or, 25y + 40 = 15

Or, y = - 25/25 = - 1.

And x = (- 4 + 10)/3 = 6/3 = 2.

That's it..

Answer 2

Step-by-step explanation:

✏3x - 4y = 10

Or, 3x = 4y + 10

Or, x = (4y + 10)/3.

➡️ 4x + 3y = 5

Or, (16y + 40)/3 + 3y = 5

Or, 25y + 40 = 15

Or, y = - 25/25 = - 1.

And x = (- 4 + 10)/3 = 6/3 = 2..
