Question

solve this mathematics problem of equation 4x+13=3x+15

Answer 1

4x + 13 = 3x + 15
4x - 3x = 15 - 13
x = 2

Answer 2

Answer:

Required solution of 4x+13=3x+15 is $x = 2$

Step-by-step explanation:

Given,

$4x + 13 = 3x + 15$

Here we want to find value of x.

First we are separating variable and constant part,

$4x - 3x = 15 - 13$

3x is Subtracting from 4x and 13 is Subtracting from 15,

$x = 2$

This is a problem of Algebra.

Some important Algebra formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
