Answer:

The solution of the equation   4x+y=5   and 3x+y=3 be (2 , -3) .

Option (D) is correct .

Step-by-step explanation:

As given the equations are .

4x+y=5

3x+y=3

Subtracted 3x+y=3 from 4x+y=5  .

Thus

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

x = 2

Put in the equation 4x+y=5  .

4 × 2 + y = 5

8 + y = 5

y = -8 + 5

y = -3

Therefore the solution of the equation   4x+y=5   and 3x+y=3 be (2 , -3) .

Option (D) is correct .

If x and y vary directly, and x=10 when y=3, what will be the value of x when y=9?
Thepotemich [5.8K]

As x and y vary directly then <span>x∝y</span> i.e. <span>x=ky</span>, where k is a constant.

When <span>x=24</span>, <span>y=8</span> i.e. <span>24=k×8</span> and therefore

<span>k=<span>248</span>=3</span>

and relation between x and y is hence <span>x=3y</span>

and when <span>y=9</span>, <span>x=3×9=27</span>.



I hope this is what you're looking for.
