Answer:

19/2

Step-by-step explanation:

3(x-6)+3=4+x

3x-18+3=4+x

2x-18+3=4

2x=19

x=19/2

[tex]3(\frac{19}{2}-6)+3=\frac{27}{2} \\4+\frac{19}{2} =\frac{27}{2}[/tex]

Answer:

x = 9.5

Step-by-step explanation:

3( x - 6 ) + 3 = 4 + x

Do the distributive property (multiply what is in the parenthesis () by 3)

3 * x + 3 * -6 + 3 = 4 + x

3x - 18 + 3 = 4 + x

Combine Like terms ( the -18 and the 3)

3x - 15 = 4 + x

Subtract x on both sides

3x - x - 15 = 4 + x - x

2x - 15 = 4

Add 15 on both sides

2x - 15 + 15 = 4 + 15

2x = 19

Divide by 2 to isolate the variable "x"

2x/2 = 19/2

x = 9.5

Check

Use substitution, now that we have the value fo "x" ( 9.5) we can substitute that into the eqaution to see if we got it correct

3( x - 6 ) + 3 = 4 + x

3( 9.5 - 6 ) + 3 = 4 + 9.5

Distribute what is in the parenthesis by 3

3 * 9.5 + 3 * -6 + 3 = 4 + 9.5

28.5 - 18 + 3 = 4 + 9.5

10.5 + 3 = 4 + 9.5

13.5 = 4 + 9.5

13.5 = 13.5

CORRECT

Hope this helped!
