If 5n - 3 = 7n – 5, then n= A -4 BO o D 6

ch4aika [34]

Answer:

The value of n is 1

Step-by-step explanation:

Given the expression $5n-3= 7n-5$

In other to solve for n we have to perform a series of step wise operations as follows

collecting like terms we have

$5n-7n= -5+3$

$-2n= -2\\$

The negative signs will council out on both sides we have

$2n= 2\\$

Dividing both sides by 2 we have

n= $\frac{2}{2}$

$n=1$
