Answer:

x = - 27

Step-by-step explanation:

Given

5(x + 3) = 4(x - 3) ← distribute parenthesis on both sides

5x + 15 = 4x - 12 ( subtract 4x from both sides )

x + 15 = - 12 ( subtract 15 from both sides )

x = - 27

Answer:

[tex]x = -27[/tex]

Step-by-step explanation:

First we simplify both sides of the equation. By using the distributive property of multiplication, we can rewrite

[tex]5 (x + 3) = 4(x - 3)[/tex]

as

[tex]5x + 15 = 4x - 12[/tex]

Now we subtract 4x from both sides:

[tex]5x + 15 - 4x = 4x - 12 - 4x[/tex]

which gives us

[tex]x + 15 = -12[/tex]

Now we subtract 15 from both sides:

[tex]x + 15 - 15 = -12 - 15[/tex]

which gives us

[tex]x = -27[/tex]
