Question

(iv) (a – 2, 2b + 1) = (b -1, a + 2)​

Answer 1

Answer:

• a-2=b-1

a-b= -1+2

a-b=1__________(1)

•2b+1=a+2

2b-a=2-1

2b-a=1

-a+2b=1______(2)

(1)+(2)=)b=2

sub. b=2 in (1)

=)a-2=1

=)a=1+2

=)a=3

Answer 2

Answer:

hope helps u

Step-by-step explanation:

Let's solve for a.

iva−22b+1=b−1a+2

Step 1: Add a to both sides.

aiv−22b+1+a=−a+b+2+a

aiv+a−22b+1=b+2

Step 2: Add 22b to both sides.

aiv+a−22b+1+22b=b+2+22b

aiv+a+1=23b+2

Step 3: Add -1 to both sides.

aiv+a+1+−1=23b+2+−1

aiv+a=23b+1

Step 4: Factor out variable a.

a(iv+1)=23b+1

Step 5: Divide both sides by iv+1.

a(iv+1)=23b+1

iv+1

iv+1

=

a=23b+1

iv+1

Answer:a=23b+1

iv+1
