1. 5x-8=2x+1
plz answer me and explain it ​

Answer 1

Answer:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

5*x-8-(2*x+1)=0

Equations which are never true:

2.1 Solve : 3 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2 Solve : x-3 = 0

Add 3 to both sides of the equation :

x = 3

Answer 2

➔ GIVEN :-

• solve the following equations and check your result in each case.
• 5x - 8 = 2x + 1

➔ ANSWER :-

$\sf{ \implies \: 5x - 8 = 2x + 1}$

$\sf{ \implies \: 5x - 2x = 1 + 8}$

$\implies \sf{3x = 9}$

$\sf{ \implies \: x = \huge \frac{ \cancel{9} {}^{ \: 3} }{ \cancel3} }$

$\huge \star \: \: \boxed{ \sf \: x = 3}$
