Question

x=3y = 4 is a solution of equation 3x + 2a + y, then find the value of a​

Answer 1

Answer:

-6.67 (-20/3)

Step-by-step explanation:

x = 3y = 4

Therefore, x = 4 and y = 4/3

Substituting these values of x and y into the given equation -

3x + 2a + y

= 3(4) + 2a + 4/3

= 12 + 2a + 4/3

Now, this equation will be equal to 0 as x = 3y = 4 is a solution of the equation.

Therefore, 12 + 2a + 4/3 = 0

2a = -12 - 4/3

Taking LCM = 3

6a = -36 -4

6a = -40

a = -40/6 = -20/3 = -6.67
