I need help with solving multi step equation homework

Question

5x - 3 = x - 12

Answer 1

5x - 3 = x - 12

 

The first step is to get all of the x values onto one side. First we can subtract an x from both sides:

4x - 3 = -12

 

Next we add 3 to both sides:

4x = -9

 

Now we divide both sides by 4, isolating x:

x = -⁹/₄

 

Now to check our answer:

5(-⁹/₄) - 3 = -⁹/₄ - 12

-⁴⁵/₄ - 12/4 = -⁹/₄ - ⁴⁸/₄

-⁵⁷/₄ = -⁵⁷/₄

Answer 2

Hi Bella,

 

5x-3=x-12

 

5x-3+3=x-12+3

 

5x=x-9

 

5x-x=x-x-9

 

4x=-9

 

4x/4=-9/4

 

x=-9/4
