Question

5x-3=21-x please someone answer ​

Answer 1

Answer:

X=4

Step-by-step explanation:

1. The first thing you would do is to make it so there is only x's on one side. To do this add the x on both sides
2. This would make it so you have 6x-3=21
3. Plus the 3 on both sides
4. This would give you 6x=24
5. Do 24÷6 giving you 4
6. X=4

Answer 2

Answer:

X=4 Hope it helps Lol

Step-by-step explanation:

  5*x-3-(21-x)=0

Step by step solution :

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  6x - 24  =   6 • (x - 4)

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    6   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    x-4 = 0

Add  4  to both sides of the equation :

                     x = 4

One solution was found :

                  x = 4
