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]
