Question

a+a=2 ,a+b=3,a+b*2=​

Answer 1

Answer:

your answer is 5

Step-by-step explanation:

a + a = 2

2a = 2

a = 1,

a + b = 3

1 + b = 3

b = 2,

a + b^2

= 1 + (2)^2

= 1 + 4

= 5

Answer 2

Method - (I)

$\tt2a = 2$

$\tt{a = \dfrac{2}{2} }$

$\tt \: a = 1........(equation - 1)$

$\tt1 + b = 3 \: \bf{(from \: equation \:1 )}$

$\tt{b =3 - 1 }$

$\tt{b = 2}$

The value of [a = 1] , [b = 2]

Now

$\tt(a + b) \times 2 = (1 + 2) \times 2$

$\tt \to3 \times 2$

$\tt \to6$

Method - (II)

This is very simple , They have given [a + b = 3] , so that , to find (a + b) × 2

we can write

[a + b] × 2 = 3 × 2
