Question

If the ordered pairs (a - 3, a + 2b) and
(3a - 1, 3) are equal, find the values of a
and b.
please answer with explanation​

Answer 1

Answer:

Correct option is

A

1

Ordered pairs (a−3,a+2b) and (3a−1,3) are equal.

It means a−3=3a−1

and a+2b=3⟶1

∴a−3a=−1+3

−2a=2⟹

a=−1

Put value of a in equation 1, we get

−1+2b=3

2b=4

b=2

a+b=−1+2=1
