Question

i) a + 2b + 2ai = 4 + 6i​

Answer 1

Answer:

Step-by-step explanation:

first compare real and imaginary parts and get the equations

a+2b=4    .....eq1

2a=6

a=6/2=3

put a=3 in eq 1

3+2b=4

2b=4-3=1

b=1/2

Answer 2

Step-by-step explanation:

a+2b+2ai=4+6i

then a+2b=4 and 2a=6

2a=6 then a=6/2=3

when a=3,

3+2b=4

2b=4-3=1

b=1/2
