Answer 1

Answer:

23)b=3,a=infinity

24)x=1/2

Step-by-step explanation:

23)a+a+a=ba -given

But we know that a+a+a=3a

From the above points we can say 3a=ba

Since a is on both sides we could eliminate them

Therefore b=3

Which leaves us with a=infinity /any value

24)3(2x+3)=8(x+1)

6x+9=8x+8

8x-6x+8-9=0

2x-1=0

2x=1

x=1/2

Answer 2

23.

$\rm \: \: \: \: A \\ \rm + A \\ \rm + A \\ \frac{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: }{} \\ \rm B A \\ \frac{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }{}$

So, by filling A = 5, we have :

$\: \: \: \:\rm 5 \\\rm + 5 \\ \rm + 5 \\ \frac{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: }{} \\ \rm 1 5 \\ \frac{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }{}$

Hence, value of A = 5 and B = 1.

$\rm \dfrac{2x+3}{x+1} = \dfrac{8}{3}$

By cross multiplication :-

$\rm \implies \dfrac{2x+3}{x+1}$ $\huge{⤱}$$\dfrac{8}{3}$

$\rm \implies (2x+3) \times 3 = (x+1) \times 8$

$\rm \implies 6x+9 = 8x+8$

$\rm \implies 6x+9 - 8x - 8= 0$

$\rm \implies -2x+1 = 0$

$\rm \implies -2x = - 1$

$\rm \implies 2x = 1$

$\rm \implies x = \dfrac{1}{2}$

Hence, value of x is 1/2.
