Question

(2n+5)=(3n-10) then n=?

Answer 1

Step-by-step explanation:

$\sf 2n + 5 = 3n - 10$

Transposing algebraic expressions in LHS and numerals in RHS will give,

$\sf \implies 2n-3n = -5 -10$

$\sf \implies -n = -15$

$\sf \implies n = 15$

Therefore, n = 15.

★Additonal info:-

Transposing the units in the equation will change the sign units. In other words, Positive integer will become negative integer on transposing and vice versa.

For example:-

x + 3 =5

x = 5-3

x = 2.

Or you can cancel 3 from both the sides.

x + 3 - 3 = 5 - 3

x = 2

Answer 2

Answer:

hey here is you answer:

Step-by-step explanation:

First you have to bring 3n in the place of 5,and 5 in front of 3n

2n+3n=5-10

then subtarct 5 from 10

you will get:

2n+3n= -5

then add 2n+3n

you will get:

5n= -5

then: (DIVIDE -5 FROM 5)

n= -5 by 5

= -1
