Question

find the value of A, B in the following 2A +3 B = B 1 a). (5,6) b). (5,5) c). (6,5) d). (6,6)​

Answer 1

Answer:

d). (6,6)......................

Answer 2

Concept Introduction:

Linear equations are those that are written in the form of ax + by + c = 0, where a, b & c are real numbers and the coefficients of x and y are not equal to no.

Given:

The given equation: 2A +3 B =  1 .

To Find:

We have to find the value.

Solution:

$Let 2a+3b=12......(1)$

and $3b$−$4$=$2$......$(2)$

On solving (2), we get

$3b$−$4$=$2$

⇒$3b$=$2$+$4$

⇒$3b$=$6$

⇒$b$=$2$

Putting b=2 in equation (1)

2a+3b=12

⇒2a+3(2)=12

⇒2a=12−6

⇒2a=6

⇒a=3

Final Answer:

The correct option is (a)
