Question

solve 5(3x – 4) = 45​

Answer 1

Answer:

5(3x – 4) = 45

15x - 20 = 45

15x = 45 + 20

15x = 65

x = 65/ 15

x = 13/3

Answer 2

Answer:

=> The value of x is $\frac{13}{3}$.

Step-by-step explanation:

Given that:-

$5(3x - 4) = 45$

To find:- The value of the expression,

For solving this expression, we must apply the transposition method:

As we have,

=> $5(3x - 4) = 45$

Now distributing the terms, we get

=> $15x - 20 = 45$

Now add both sides by $20$, we get

=> $15x - 20+20 = 45+20$

Simplifying it further, we get

=> $15x = 45+20$

Add the numbers, we get

=> $15x = 65$

Divide both sides by $15$,

=> $x = \frac{65}{16}$

Canceling the terms, we get

=> $x = \frac{13}{3}$

Hence, the required solution is $\frac{13}{3}$.
