Question

when a=3 and b=-4 then a+b/a-b=​

Answer 1

Answer:

a+b=7

a-b=-1

Step-by-step explanation:

a=3

b=4

1.

a+b=

3+4=7

2.

a-b=

3-4=-1

Answer 2

$\rm {Solution} \rightarrow$

$\tt\rightarrow \: \frac{a + b}{a - b} = \frac{3 + ( - 4)}{3 - ( - 4)}$

$\tt\rightarrow \: \frac{3 - 4}{ 3 + 4}$

$\tt\rightarrow \frac{ - 1}{ - 7}$

$\tt\rightarrow \frac \red{1} \red{7}$
