Question

for simultaneous equation in variable x and y dx =27and dy=-36 if d=3 what is the value of x?​

Answer 1

✠ Given :

• For simultaneous equation in variable x and y dx =27and dy=-36 if d=3.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

✠ To find :

• what is the value of x?

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

➬ we have,

• dx = 27 , dy = -36 and d = 3

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

✠ SOLUTION :

∴ dx = 27

Put d = 3

Then we get,

$→3 \times x = 27$

$→x = \frac{36}{3} =12$

$→x = 12$

• And if dy = -36

$→3 \times x = - 36$

$→x = - 36$

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

✠ Hence ,

• The value of x is 9.
