Answer 1

Answer:

a = 3/2

LCM=2

2a/2 + 7/2 = 10/2

2a/2 = 10-7/2 = 3/2

Therefore, a= 3/2 × 2/2 = 3/2

Hope this helps..

Answer 2

$\bold{\LARGE{\underline{\underline{Answer:–}}}}$

a = 5

_____________________

$\bold{\LARGE{\underline{\underline{Explanation:–}}}}$

$a\:+\:3\:\frac{1}{2}\:=\:5$

$a\:+\:\frac{7}{2}\:=\:5$

$a\:+\:7\:=\:5\: ×\:2$

$a\:=\:10\: -\:7$

$a\:=\:3$

.

Let's verify !

a = 3

.

LHS

$3\:+\:3\frac{1}{2}$

$=\:3\:+\:\frac{7}{2}$

$=\:\frac{3}{1}\:+\:\frac{7}{2}$

$=\:\frac{3\:+\:7}{2}$

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

$=\:5$

.°. LHS = RHS = 5

Hence, verified
