Question

if a+b=2 and a-b=0 what is a and b​

Answer 1

${\bold {\boxed{\underline {\huge {\green {Answer :}}}}}}$

given:

$a + b = 2$

$a - b = 0$

by elimination method

we get,

$2a = 2 \\ a = 1 - - - - (1)$

by putting the value of a in first expression

$1 + b = 2 \\ b = 2 - 1 \\ b = 1$

so the values are

$a = 1 \\ b = 1$

Answer 2

Answer:

Step-by-step explanation: a+b=2 (1)

a-b=0(2)

So from eq1and2

2a=2

So ..a=1

And from eq1

a+b=2(put value of (a)

Than 1+b=2

B=2-1

B=1

So a=1and b=1 also
