Question

find the values of the following 5x+3y when x=2 and y=3​

Answer 1

Answer:

Given, (5x−3y,y−3x)=(4,−4)

Hence, 5x−3y=4 ----- equation (1)

and y−3x=−4 ----- equation (2)

Multiplying both sides of the equation (2) with 3 we get, 3y−9x=−12 ----- equation (3)

Adding equations (1) and (3), we get −4x=−8=>x=2

Substituting x=2 in the equation (2), we get y−3(2)=−4=>y=2

Hence, x=2;y=2

Answer 2

$\mathbb{QUESTION}$

Value of 5x + 3y

$\huge{\mathtt{ANSWER}}$

$\bf{given}$ ,

x = 2

y = 3

$\therefore$ A/Q

$\implies$ 5x + 3y

$\implies$ ( 5 × 2 ) + ( 3 × 3 )

$\implies$ 10 + 9

$\implies$ 19
