Question

If a-b =12 and b/2=10 what is the value of a+b

Answer 1

Answer:

The value of a + b is 52.

Step-by-step explanation:

Given equations,

$a-b = 12$

$\frac{b}{2}=10$

$\implies b = 20$

By substituting the value in the first equation,

$a - 20 = 12$

$\implies a = 12 + 20 = 32$

Hence,

$a+b=32 + 20 = 52$

$\red { Value \: of \: a + b = 32 + 20} = \green {52}$

Step-by-step explanation:

$Given \: \blue { a-b=12\: ---(1)} , \\\pink {\frac{b}{2}=10}$

$\implies b = 2\times 10$

$\implies \pink { b = 20\:---(2)}$

\* Substitute b = 20 in equation (1) ,we get

$a - 20 = 12$

$\implies a = 12 + 20 = 32$

Therefore.,

$\red { Value \: of \: a + b = 32 + 20} = \green {52}$
