Answer: it has no solution

Step-by-step explanation:

8x - 2y = 1 ..................... equation 1

-4x + y = 3 ...................... equation 2

solving the system of linear equation by substitution method . From equation 2 , make y the subject of the formula.

y = 3 + 4x .......................... equation 3

substitute equation 3 into equation 1 .

8x - 2(3 + 4x ) = 1

8x - 6 - 8x = 1

8x- 8x - 6 = 1

-6 = 1

this means that the equation has no solution

D/18 + 3 = 3d/54 + 22

Anestetic [448]

Answer:

But this condition is not feasible so, from given equation the value of D is not determine

Step-by-step explanation:

Given equation is :

$\frac{d}{18} +3 = \frac{3d}{54} + 22$

$\frac{d}{18} - \frac{3d}{54}$ = 22 - 3

Or, $\frac{3d -3d}{54}$ = 18

Or 0 = 18

But 0 ≠ 18

but this condition is not feasible so, from given equation the value of D is not determine .. Answer
