Question

If 4x + 3y - 2a = 2 for x=-2 and y = 2, then find the value of a .​

Answer 1

Answer :-

Value of a is - 2.

Explanation :-

4x + 3y - 2a = 2

Here

• x = - 2

• y = 2

By substituting the given values in the above equation

⇒ 4(-2) + 3(2) - 2a = 2

⇒ - 8 + 6 - 2a = 2

⇒ - 2 - 2a = 2

⇒ - 2 - 2 = 2a

⇒ - 4 = 2a

⇒ - 4/2 = a

⇒ - 2 = a

⇒ a = - 2

∴ the value of a is - 2.

Answer 2

Answer:

Step-by-step explanation:

Given x = -2 and y= 2

now, 4x +3y - 2a = 2

Putting the values,

4×(-2) + 3×2 - 2a =2

-8 + 6 -2a=2

-2 -2a=2

-2a = 2+2

-2a = 4

a = 4/ -2

a =-2 (ans)
