Question

14=3y+x; 20=2y-3xsolution this equation

Answer 1

Answer:

Here's your answer

Step-by-step explanation:

14 = 3y + x  ---------- (1)

20 = 2y - 3x ---------- (2)

From eq (1) we get,

x = 14 - 3y ---------------- (3)

Now , put the value of x in eq(2)

we get ,

20 = 2y - 3x

=> 20 = 2y - 3(14 - 3y)

=> 20 = 2y - 42 - 9y

=> 20 - 42 = 2y - 9y

=> -22 = -7y

canceling (-) sign from both the sides

=> 22 = 7y

=> y = 7/22

Now put the value of y in any of the 3 equations

we will put in eq (3)

x = 14 - 3y

x = 14 - 3 * 7/22

x = 14 - 21/22

x = 308 - 21/22

x = 287/22

Hope you understand.
