Question

If A+A+A=BA, Then find the value of A and B​

Answer 1

Answer:

a=1 and b = 3

Step-by-step explanation:

A +A + A = BA

3A = BA;

SOLVE FOR B

B = 3A/A

B = 3;

SUBSTITUTE VALUE FOR B IN EQUATION

AND SOLVE FOR A

3A = 3A, A = 1

ANSWER B = 3,

A = 1

CHECK

3(1) = 3(1)

Answer 2

There are two cases.

Case 1: A is not equal to 0

Assuming

++=
A
+
A
+
A
=
B
A

Combining the A’s on the left side, we get:

3=
3
A
=
B
A

Dividing both sides by A, we arrive at:

=3
B
=
3


A
can be any number it wants to be in this case.

Case 2: A is equal to 0

In this case, our equation simplifies to:
0=0∗
0
=
0
∗
B

We get =0
A
=
0
and
B
can be any number.
